S.T.A.R. VS7550 VUV/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.  For VUV operation, the spectrograph has a UHV window and laminar flow purge system, which allows operation down to the window short wavelength cut-off (112 nm for MgF2).  Small enough to fit in your hand, it 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 and low-cost accessories such as telescopes, vacuum adapters, and flow controllers.
