Software for SPECTRAL EVOLUTION spectrometers and spectroradiometers

Every SPECTRAL EVOLUTION Spectrometer and Spectroradiometer is supplied with the exclusive DARWin SP Data Acquisition software – a full-featured, menu driven program for easy data manipulation and analysis of multiple UV/VIS/NIR spectra. The DARWin SP module features one-touch operation and easy, intuitive menus for fast, effortless operation. DARWin saves your scans as ASCII files for use with third party software, like SpecMIN, TSG, and GRAMs, without pre-processing.

DARWin SP features the following capabilities:

Data Collection:
  • Collect reference or target scan spectra with a single click
  • Automatic shutter for dark compensation
  • Automatic integration time adjustment for each detector, or user can set values manually
  • User-selectable averaging
  • User-selectable radiometric calibration for instruments supplied with multiple entrance optic accessories
  • Instrument status displayed after each scan (voltage, temperature, scan title, etc.)
  • Automatically saves spectra to text files for later retrieval
  • Timed mode: spectra can be collected at user adjustable intervals from 1 second to 1 hour.
  • Trigger mode: instruments equipped with external trigger inputs can collect data when receiving a trigger signal, with adjustable 0-50 ms delay
Plotting Data:
  • Spectrometry – display reflectance/transmittance data (percentage) or absorbance (logarithmic) vs. wavelength
  • Spectroradiometry – display spectral radiance or irradiance vs. wavelength, depending on entrance optic
  • Two types of spectral plots available: single and multiple
  • Single scan plot displays active spectrum (radiometric/ratio/both with separate y-axes), with or without the associated reference.
  • Single scan plot also features a data table window with user-selectable columns (channel #, wavelength, radiometric/ratio values for both reference and active spectra)
  • Table data can be easily copied to spreadsheet software
  • Multiple scan plot displays numerous scans on the same axes; easily compare current scans against ones collected over an extended time period or archived data
  • Selectable plot lines highlight the corresponding legend items. Selectable legend titles allow you to hide/show/delete plot lines or copy them to new plot windows
  • All plots have automatic or manual vertical scaling adjustment and axis limits
  • Zoom and pan functionality. Single scan plots can zoom multiple y-axes together or independently
  • Adjustable plot titles, axis labels, color palettes, line thickness and antialiasing
  • Optional adjustable-width moving average filtering
Scan Information Window:
  • Displays up-to-date instrument parameters (device ID, voltage, detector temperature readings)
  • Displays current scan parameters (title, averages setting, integration settings, dark current subtraction mode)
  • Spectroradiometry: integrated radiance or irradiance, with user-adjustable wavelength range and display units
  • Photometry: luminance/illuminance
  • Colorimetry: x’,y’ coordinates and correlated color temperature

DARWin SP includes:

DARWin SP is also available in two additional versions:

DARWin SP is also available with sample identification software:

EZ-ID for mineral identification allows you to collect a scan from an unknown target and match it to a known mineral scan from the USGS spectral library, SpecMIN, GeoSPEC or other commercial spectral libraries, or a custom library you can build with the Custom Library Builder module that is part of EZ-ID.

DARWin SP offers 19 vegetation indices in a pull-down menu for researchers working in a range of vegetation studies, crop health projects, canopy studies, and more.

DARWin SP Data Acquisition software is easy to use with intuitive menus and a range of capabilities for capturing scans in the field, like the leaf scan shown above.
