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.
