AvaBench Optical Benches - OEM
AvaSpec spectrometer components can also be provided as separate products to be used in OEM applications. Avantes has developed 3 types of optical benches especially for OEM customers.
The optical benches AvaBench-45, AvaBench-50 and AvaBench-75 are symmetrical Czerny-Turner designs with fibre optic entrance connector (as standard SMA - other types are possible), collimating and focussing mirror and diffractional grating.
A choice of different gratings with different dispersion and blaze angles enable applications in the 200-2200nm range.
Wavelength ranges, resolution tables, detector specifications and AvaBench options can be found in the relevant sections on the AvaSpec products.
In the table below, the main differences between the optical benches are illustrated.
