S.T.A.R. VS7550 UV Mini Spectrograph Spectrometers
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.
