Real-Time Imaging Spectroscopy Software
KestrelSpec™ ST-135 software is designed for data acquisi-
tion and analysis in CCD imaging spectroscopy applications
with the ST-135 CCD Camera (GPIB interface) from Princeton
Instruments, Inc., and your Macintosh® computer. Spectrograph Camera Head
u Data Acquisition
• Real-time-, dark-background- and flat-field- image buffers.
• Up to 30000 curve memories in RAM for spectral plotting and
• Select arbitrary areas from the CCD for spectral curves.
• Select CCD pixel-grouping (binning) modes. Add a spectrograph and a Macintosh to complete your

• Scan rate up to 100 frames/s, depending on CCD binning
mode, number of image stripes and Macintosh CPU speed.
• Up to 18 bits per pixel image digitizer presision.
• Programmable exposure sequence with adjustable delay
intervals. Sum multiple image exposures into curve memories.
• Automatic background subtraction, flat-field correction of
images and curves.
* Auto-flip image horizontal (for reverse spectral dispersion).
• Conversion of data to log or absorbance scales.
• Auto-save images, curves to disk or RAM disk.
• Auto-scan λ, auto-calibrate spectra in nm, Raman cm-1 shift
with fully integrated spectrograph control (optional extra).
