SearchLight™ Spectrum Plotting Tool Support

Welcome to SearchLight!

We are proud to release this online plotting tool designed for the research scientist working in fluorescence microscopy or the optical instrument designer working on next generation fluorescence-based systems. SearchLight allows you to easily select elements for your system, visualize the spectral properties, and quickly calculate critical parameters such as signal brightness, autofluorescence levels, and signal-to-noise ratio. With an intuitive interface one can easily test filter set compatibility with various fluorophores, see the effects of changing system components (light sources, detectors, objectives), or create custom arrangements for a unique application.

SearchLight contains an extensive library of 955 fluorophores, 218 light sources, 75 detectors, and Semrock’s entire library of 889 filters and 148 optimized sets. You may also upload your own custom dataset for any components not currently included as a selection choice.

SearchLight can also save all of your results, custom data uploads and configurations to save you time when you return. You can also download each project to your computer and easily share important data with co-workers.

To get you started, we have produced a short video to help guide you through the component selection and results viewing process.

We hope you find this online tool valuable and encourage you to send us an email and share your comments to SearchLight@idexcorp.com.

System Requirements

The SearchLight plotting tool is optimized for Microsoft Internet Explorer 9 or higher, Google Chrome, Mozilla Firefox, and Apple Safari with JavaScript and cookies enabled. Due to the advanced HTML features required, earlier versions of Internet Explorer might not perform as optimally. The minimum recommended screen resolution is 1280 pixels wide, though it will function with fewer pixels.

Layout

SearchLight is comprised of a single screen with four main sections:

• Data Input (top left): Select from the extensive database of spectra for Filters, Filter Sets, Fluorophores, Light Sources, and Detectors. Enter your own spectra in My Data.
  
• Plotting Window (top center): View an unlimited number of spectra loaded into the Plotting Legend section, overlaid on a single, convenient graph. The Plotting Window enables rapid visual estimation of the compatibility among filters, fluorophores, light sources, and detectors.
  
• Plotting Legend (top right): Keep track of and modify spectra that are loaded into the active SearchLight environment. Select which spectra to view, modify plot characteristics, download spectra as ASCII data to your local computer environment, and remove spectra from the active SearchLight environment.
  
• Calculators (bottom): Evaluate absolute and relative signals (i.e., brightness or system throughput) and signal-to-noise ratios (contrast) for an unlimited number of combinations of filters, fluorophores, light sources, and detectors.
  

Data Input

Available spectra:

• Filters: Select from all available Semrock catalog filters. Filter spectra are based on theoretical designs of Semrock filters. Design (rather than measured) spectra are used to obtain the most accurate calculated results, since real measurement limitations and artifacts result in measured filter spectra that do not accurately represent the true edge steepness and optical density of a fluorescence filter.
• Filter Sets: Select from all available Semrock catalog filter sets, including single-band bandpass and long-wave-pass sets and multiband sets.
• Fluorophores: Select from an extensive list of fluorophores. Spectra are sourced primarily from the University of Arizona (www.spectra.arizona.edu) and Invitrogen (www.invitrogen.com). Fluorophore text file headers contain more source details.
• Light Sources: Select from a list of lamp, laser, LED, and other solid-state light source spectra. Spectra are based on manufacturer published data as well as measured data.
• Detectors: Select from a list of commonly used detectors. Detector spectra are based on manufacturer published data.
• My Data: Upload your own spectra (filters, fluorophores, light sources, and detectors) or model a bandpass filter or long-wave-pass dichroic beamsplitter spectrum. Uploading user data requires an Account. Files to upload should be ASCII text data with two tab-delimited columns The first column should contain wavelength values (in nm), and the second column should contain spectrum values (between 0 and 1). Text headers above the column data will be retained for your reference. Comments should be preceded by a "%"

Select spectra and load into SearchLight environment:

• Click the title bars containing the names of the different spectra types to expand a list of those spectra.
• Click once on the name of a spectrum in the list to preview (in light gray) a version of that spectrum in the Plotting Window.
• Double-Click the spectrum name or click the arrow to the right of the spectrum name to add the spectrum to the Plotting Window and Plotting Legend.

• Click on the arrow on the right-hand edge of the Data Input section to minimize (hide) or expand (show) the section.

Intelligent User Experience

Overview

SearchLight utilizes sophisticated algorithms to provide enhanced user experience. For example, you can Find compatible products for a selected fluorophore to narrow down a list of potentially compatible exciters, emitters, dichroics or filter sets.

This function helps narrow down the list of filters however user judgement is required in optimal filter selection based on application needs. Current algorithms are optimized for broadband light sources and we are continuing to make improvements for other illumination sources such as LED based Light Engines and lasers.

Calculators

A SearchLight Calculator quantitatively computes the fluorescence signal, noise, and signal-to-noise ratio for unlimited combinations of filter sets, fluorophores, light sources, and detectors. Calculations are based on a straightforward mathematical framework, which is described in detail in the white paper Spectral Modeling in Fluorescence Microscopy. Besides the main spectra, additional system input parameters include other spectrally dependent losses in the system, the collection efficiency of the optics, and characterization of the fluorophores by quantum yields and decadic molar extinction coefficients.

The power of the SearchLight Calculator is that it enables quantitative evaluation of the compatibility of filter sets with fluorophores and other spectrally dependent components of a system, analysis of crosstalk and bleedthrough, identification of optimal spectral edge locations for a set of filters under specific experimental conditions, and guidance regarding labeling protocols in multiplexing imaging assays. These analyses can be simultaneously conducted on multiple system configurations by creating multiple Calculators, thereby enabling multidimensional design-of-experiment analyses.

The Calculator assumes the following typical epifluorescence microscope configuration with spectral features described in detail below. The calculations are also applicable to nonimaging systems, as well as to nonepifluoresence configurations. For example, it is not necessary to include the dichroic beamsplitter (when absent, its transmission and reflection spectra are assumed to be unity for all wavelengths).

Schematic diagram of a typical epifluorescence microscope configuration based on optical filters (left), and examples of absorption and emission spectra for a target fluorophore, transmission spectra for a set of optical filters, and light source and detector spectra (right). The light source (black) is a xenon arc lamp with the detector response profile (brown) representing a typical (cooled) CCD camera. See Spectral Modeling in Fluorescence Microscopy for additional details.

Calculator Inputs

• Name: The name of an instance of the Calculator. The name can be changed.
• Filter Set: The name of a 3-filter set. While an actual filter set can be comprised of multiple exciters and emitters, for the Calculator a set is assumed to consist of a single exciter, a single emitter, and a dichroic beamsplitter. Selecting a filter set that is loaded into the Plotting Legend automatically populates the exciter, emitter, and dichroic that are associated with that filter set into the drop-down lists below. For multiband sets, by default the first exciter and first emitter in the list are selected, but these can be changed.
• Exciter: The name of the excitation filter. This field is populated by default when a filter set selection is made. It is also possible to designate any individual filter as an exciter, even when it is not part of a filter set. The exciter spectrum is represented as T_X(λ) in the diagram above.
• Emitter: The name of the emission filter. This field is populated by default when a filter set selection is made. It is also possible to designate any individual filter as an emitter, even when it is not part of a filter set. The emitter spectrum is represented as T_M(λ) in the diagram above.
• Dichroic: The name of the dichroic beamsplitter. This field is populated by default when a filter set selection is made. It is also possible to designate any individual filter as a dichroic, even when it is not part of a filter set. The dichroic spectrum is represented as T_D(λ) and R_D(λ) in the diagram above, corresponding to the transmission and reflection spectra of the filter, respectively. Only transmission data is necessary to characterize the dichroic, since it is assumed that R_D(λ) = 1 – T_D(λ).
• Fluorophore: The name of the fluorophore. A fluorophore spectrum is comprised of two distinct spectra: the absorption spectrum and the emission spectrum. These spectra are loaded by default into the Fluorophore Absorption and Fluorophore Emission fields when a Fluorophore name is selected. To load a custom fluorophore into the My Data list in the Data Input section, it is required to load the (normalized) Fluorophore Absorption and Fluorophore Emission spectra as two separate data files. To provide a Fluorophore DMAC, add the following header to the absorption file: # DMAC: <number> . To provide a Fluorophore Quantum Yield, add the following header to the emission file: # Quantum Yield: <number between 0 and 1>.
• Fluorophore Absorption: The absorption spectrum of the fluorophore. This field is populated by default when a Fluorophore selection is made. The absorption spectrum is represented as φ_A(λ) in the diagram above. It is normalized such that the value at the peak absorption wavelength is equal to 1.
• Fluorophore Emission: The emission spectrum of the fluorophore. This field is populated by default when a Fluorophore selection is made. The emission spectrum is represented as φ_E(λ) in the diagram above. It is normalized such that the value at the peak emission wavelength is equal to 1.
• Light Source: The spectrum of the selected light source. For display purposes only, SearchLight automatically normalizes the displayed spectrum such that the peak value is equal to 1. However, for calculations SearchLight normalizes the area under the curve so that the total power integrated over all wavelengths is equal to the value entered in the Advanced inputs section of the Calculator. The Light Source spectrum is represented as L(λ) in the diagram above.
• Detector: The detector spectral response profile. The detector spectrum is represented as D(λ) in the diagram above. For CCD and CMOS cameras, the peak value of the detector response spectrum is assumed to be the peak quantum efficiency of the camera, whereas for all other types of detectors the spectrum is normalized such that the peak value is 1. This normalization convention should be kept in mind when loading a custom Detector spectrum into the My Data list in the Data Input section.

Advanced Inputs

• Light Source Power (mW): The total power of the excitation light source integrated over all wavelengths. It is represented as P_L in the diagram above.
• Numerical Aperture: The Numerical Aperture (NA) of the objective lens which collects the fluorescence emission from the sample. The system is assumed to collect fluorescence from the sample over a solid angle (in steradians) of
  
  
  where n is the index of refraction (see below). Thus the fraction of total fluorescence emitted from the sample that is captured by the objective is Ω / 4π.
• Index of Refraction: The index of refraction of the medium between the objective lens and the sample. See Numerical Aperture above to understand the impact of the index.
• Reflected Excitation Light Factor: An empirical factor introduced to take into account the amount of excitation light that is redirected from the excitation path into the emission path (primarily by reflection off of the sample and its supporting glass). A default value of 0.07 assumes that 7% of the excitation light is redirected from the excitation path into the emission path. This value is assumed to be independent of wavelength. It is represented by the factor ƒ_ER in the white paper.
• Transmitted Excitation Light Factor: An empirical factor introduced to account for the transmission spectrum of all other optics in the excitation light path. A default value of 0.95 assumes that the optics in the excitation light path (with the exception of the exciter and dichroic) have 95% transmission. This value is assumed to be independent of wavelength. It is represented by the factor T_i(λ) in the diagram above.
• Fluorophore Optical Depth (M cm): The product of the molar concentration of target fluorophore ("c" with dimensions of M = molar = moles/liter = 10^-3 moles/cm³) and the thickness of a slab of fluorophore ("d" with dimensions of cm). That is, Optical Depth = c×d. This term can be used to optimize the ratio of fluorophore labeling concentrations in order to minimize bleedthrough, for example.
• Fluorophore DMAC (M^-1cm^-1): Maximum value of the decadic molar extinction coefficient (or decadic molar absorption coefficient, DMAC) for the target fluorophore. This quantity is a property of the fluorophore and its value is normally available from the fluorophore manufacturer. SearchLight Calculator automatically populates this value for the selected fluorophore when it is available in the associated data file. When this value is not available, it is assumed to be 80,000 and the DMAC field is highlighted in yellow. To correctly calculate crosstalk between fluorophores, the correct DMAC value must be used. The fluorophore DMAC is represented as ε_10,peak in the diagram above. Note that Fluorophore DMAC × Fluorophore Quantum Yield is a measure of the brightness of a fluorophore.
• Fluorophore Quantum Yield: The Quantum Yield for the target fluorophore. This quantity is a property of the fluorophore and its value is normally available from the fluorophore manufacturer. SearchLight Calculator automatically populates this value for the selected fluorophore when it is available in the associated data file. When this value is not available, it is assumed to be 0.5 and the Quantum Yield field is highlighted in yellow. To correctly calculate crosstalk between fluorophores, the correct Quantum Yield value must be used. The Quantum Yield is represented as η_F in the diagram above. Note that Fluorophore DMAC x Fluorophore Quantum Yield is a measure of the brightness of a fluorophore.
• Autofluorescence Light Factor: An empirical factor introduced to take into account the relative strength of autofluorescence signal to the desired fluorescence signal. Its recommended value should be between 0 and 1. The default value of 0.1 assumes that the autofluorescence signal strength is 10% of the desired signal. This value is assumed to be independent of wavelength. Examples of sources of autofluorescence in imaging systems include the sample and its supporting glass, the primary objective and other lenses, optical filters, and any other optical elements. The Autofluorescence Light Factor is represented as ƒ_AF in the white paper.
• Transmitted Emission Factor: An empirical factor introduced to account for the transmission spectrum of all other optics in the emission light path. A default value of 0.95 assumes that the optics in the emission light path (with the exception of the dichroic and the emitter) have 95% transmission. This value is assumed to be independent of wavelength. It is represented by the factor T_o(λ) in the diagram above.

Calculator Outputs

• Fluorescence Signal (mW): The total desired fluorescence signal that reaches the detector (just before the photons get converted to electrons). Note that the light input to the Calculator is expressed in mW and therefore the signal output is also expressed in mW. The Signal is represented by S in the white paper.
• Excitation Light Noise (mW): The undesired noise power that reaches the detector and which results from transmission and reflection of the excitation source light through the system, including reflection off of the sample as quantified by the Reflected Excitation Light Factor. This quantity is very sensitive to the overlap and edge steepnesses of the excitation and emission filters as well as the level and extent of out-of-band blocking in these filters. It is represented as N_E in the white paper.
• Autofluorescence Noise (mW): Total noise power that reaches the detector and which results from undesired autofluorescence. It is represented as N_AF in the white paper.
• Signal-to-Noise Ratio: The optical signal-to-noise ratio (SNR), equivalent to the Fluorescence Signal divided by the sum of the Excitation Light and Autofluorescence Noise values. Note that the calculated SNR takes into account only the optical signal and sources of optical noise. The calculation does not account for electrical noise which results when photons are converted into electrons in an actual detector (shot noise, dark counts, etc.). To compute the signal-to-autofluorescence-noise ratio only, simply set the Reflected Excitation Light Factor to 0. To compute the signal-to-excitation-light-noise ratio only, set the Autofluorescence Light Factor to 0.

Calculator Controls

• Link to plot window (next to the Calculator Name): When this button is checked in a given Calculator, only the inputs from this Calculator are checked in the Plotting Legend and displayed in the Plotting Window. The button may be checked in only one Calculator at a time. Checking this button is equivalent to selecting a Calculator name from the drop-down list in the Plotting Legend header.
• Normalize other Calculators relative to these values (below the Outputs): This feature is extremely useful. For most practical cases there is insufficient system knowledge to obtain accurate absolute values for Signal and Noise, yet relative comparisons among different filter-fluorophore-component spectra combinations can be highly accurate. By checking this button in a particular Calculator, the values for Signal, Excitation Light Noise, etc. in all other Calculators will be normalized to their respective values in the Calculator with the button checked.

Optimization Calculators

"Optimization Calculator" enables Calculator outputs as a function of variation in the spectral edge locations of filters. For example, spectral edge of a filter can be varied over a range, specified by Input Array, to calculate an array of Fluorescence Signal, Noise, and Signal-to-Noise Ratio. Any combination of Exciter, Emitter and Dichroic spectra can be simultaneously selected for such simulations.

Here is an example of how to use this feature. Let us say, one needs to calculate change in Fluorescence Signal, when the Short Wave Pass (SWP) edge of the FITC-3540C emitter is varied over a range of -10 to +20 nm with respect to the nominal design. That is, calculate an array of Fluorescence Signal values when the highlighted edge (thick blue line) in the following plot is shifted over a range of -10 to +20 nm (denoted by red arrows) from the nominal design. Note that the nominal design of a filter refers to the filter selection in the corresponding Calculator.

In order to setup above parameters for simulation, switch to the "Optimization Calculator" tab which assumes same system parameters as listed in the corresponding "Calculator". Then follow these steps:

1. Select Emitter as the filter for simulation.
2. Specify filter spectra range (in nanometers) over which existing spectral edge of the filter needs to be adjusted.
3. Specify the range of variation (-Shift in nm and +Shift in nm with respect to the nominal design). Here, -Shift denotes a shorter wavelength and +Shift implies longer wavelength.
4. Specify step size for calculation.
5. Click the Calculate button to obtain the results of the simulation.

That is, Optimization Calculator input appears as below (a single row of Input Array):

To help with visual guidance, once the above information has been populated in the Optimization Calculator, display of the spectral plot changes as below. In this figure, the selected spectral feature is highlighted in blue (a thicker line), and the range of simulation is denoted by the patterned diagonal lines.

The above example can be accessed in this SearchLight session: Example Session

Following are examples of additional features of Optimization Calculator:

• Spectra of Exciter, Emitter and Dichroic can also be selected simultaneously to calculate impact on Outputs
• Multidimensional Array Calculations can be performed by creating multiple instances (or rows) of Input Array (1 <= # of Input Arrays <= 3)
