AvaSpec optical benches are available with or without one of our electronics boards for integration into customers’ systems. Avantes has developed four types of UV/VIS optical benches, especially for OEM customers. The optical benches AvaBench-75-ULS (used in both StarLine and SensLine), AvaBench-75-MN (CompactLine), AvaBench-75-ULSTEC (SensLine), AvaBench-37.5-HS (SensLine) and AvaBench-100-HSC (SensLine) are Czerny-Turner designs with fiber-optic entrance connectors (standard SMA, others possible), collimating focusing mirrors and a diffraction grating. A choice of different gratings with different dispersions and blaze angles enable applications in the 200 to 1160 nm range.
Our new miniature bench is perfect for OEM integration in existing systems and handheld devices. The high numerical aperture AvaBench-37.5-HS has full mechanical compatibility for mounting holes with the AvaBench-75-ULS, which makes it convenient for OEM customers to upgrade to a higher-throughput optical bench.
Wavelength ranges, resolution tables, detector specifications and AvaBench options can be found in the instrument page corresponding to each spectrometer type. In the table below, the key specifications of these optical benches are listed.
All AvaBench optical benches are fully compatible with Avantes’ electronics boards or may be interfaced to customer specific electronics. Video output is handled through a separate mini-coax cable.
