DARWin SP Data Acquisition software adds first and second derivatives capabilities

Lawrence, MA  – DARWin SP Data Acquisition software is included with every SPECTRAL EVOLUTION spectrometer and spectroradiometer. The software controls the instruments and provides additional capabilities via pull down menus. Now, DARWin SP Data Acquisition software offers first and second derivatives calculations.

Derivatives are typically used as signal pre-treatments applied to spectra data. They help to resolve peak overlap, enhance resolution of spectral features and eliminate noise & spectral drift between samples. Shown below is an example of the first derivative for a vegetation scan.

 

The following scan shows derivatives of the mineral lepidolite.

 

 

The first and second derivatives are easily accessed by identifying the spectra they will be applied to and sending the scan to the derivatives window.

DARWin SP features one-touch operation and easy, intuitive menus for fast, effortless operation. In addition to derivatives, DARWin SP also offers easy access to 19 vegetation indices, mineral reflectance, solar simulation, colorimetry, and energy measurement.
