VS7550
UV to NIR Mini-Spectrograph
The VS7550 is a miniature Czerny-Turner spectrograph with
excellent speed, spectral range and spectral resolution with
software control of slit size, input f#, order sorting filters, grating
angle and dark exposures. The UV spectrograph has a spectral
range from the air short wavelength cut-off at 185 nm to the
detector IR cut-off at 1100 nm. The spectrograph is small
enough to fit in your hand and can be fully operational in any
orientation at the end of a 5-meter cable. Accessories include a
built-in spectral calibration lamp, a multi-spectral field flat light
source, fiber optic adapters and back thinned detectors.
