KestrelSpec Software for CCD Spectroscopy

KestrelSpec imaging-spectroscopy software is available in a variety of versions that control CCD detectors and spectrographs from popular vendors. See our product-list page for supported detector and spectrograph hardware.

A sample 3D-spectra display in KestrelSpec is shown below.
(The lower, small window is the Control Palette.)

KestrelSpec includes flexible means for automatically converting CCD data into spectrum graphs. A variety of data visualization features are built into the software, including:

3D surface plots
2D overlays
channel-profile plots (z-axis slice, or "y(t)")
stacked plots
spectrum catalog with mini "thumbnail" view of spectra which can be cut and pasted.

Image views include grayscale (negative and positive) as well as 23-level pseudocolor wiith color-coded intensity legend. A "beam profiler" image view is also built into KestrelSpec.

The data-acquisition secquence from the CCD detector can be programmed with KestrelSpec's dialog windows. Select number of image frames, delay between frames, number of scans, trigger options, as well as exactly how curves will be assigned and co-added from images. Hardware (on-chip) and software (in the computer) pixel grouping can be combined in order to get exactly the pixel-binning scheme desired.

Spectral processing includes:

spectrum baseline-fitting and subtraction
spectral stretching and renormalization (arbitrary linearization of nm or cm-1 interval per point)
automatic joining of two or more spectra that overlap in wavelength (or Raman shift)
transformation of transmission spectra to absorbance (O.D.) units

as well as other standard math operations.

KestrelScript - The scripting system for KestrelSpec software, which is a standard feature, lets you send commands to KestrelSpec from another program, including National Instruments' LabView (R). KestrelScript commands include standard menu items as well as other instructions which transfer spectral data from KestrelSpec to the controlling program, adjust the wavelength calibration of KestrelSpec, etc. KestrelScript effectively lets you use KestrelSpec as a very high-level driver for the CCD.


Download Demo Versions of KestrelSpec:

Download the Macintosh KestrelSpec Demo, (requires Stuffit Expander).

Also download the Macintosh KestrelSpec software manual, which is in Adobe Acrobat format. (This link is to an Acrobat copy of the Mac-version manual. To view the manual you will need the Adobe Acrobat reader for your computer; get a free copy of the Acrobat Reader from the Adobe web site.)
 

Download the Windows KestrelSpec Demo (available for Win 9X, Me, Win NT, 2000 - this is a link to the Catalina Scientific site). You can also download various versions of the KestrelSpec for Windows manual at this link.

The Mac demo will operate the ST-6I or ST-6V CCD, and acquire data just as the fully functional version does, but it will not save data files.

The Windows demo will open sample data files (included in the download package) and allow you to explore many of the data visualization and processing features of KestrelSpec.

These demo versions of KestrelSpec do not include the various control options for spectrographs, which are available in the fully-functional software.

Demo copies of other versions of KestrelSpec (for other CCDs, or for the SE 200 spectrograph) are available without charge. Contact us if you are interested in a free demo copy of KestrelSpec for use with a particular model of CCD.
