OEM Spectrometers: AvaBench NIR Optical Benches
 
||| |||

For OEM applications in the NIR region, Avantes offers our line of AvaBench NIR optical benches. The AvaBench-50 optical bench is available in the 1000 to 1750 nm range for uncooled detectors. New in this line is the AvaBench-100TEC: a 100 mm optical bench offering optimal balance between optical throughput and resolution. To keep the size compact, it has a unique folding mirror built into it.

All AvaBench NIR optical benches have a symmetrical Czerny-Turner designs with a fiber-optic entrance connector (standard is SMA, other options are possible), a specially designed collimating focusing mirror and a diffraction grating. A choice of different NIR gratings can be selected with the products.

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 the NIR optical benches are listed.

The NIR AvaBenches are fully compatible with Avantes' electronics boards or may be interfaced to customer specific electronics. The NIR optical benches have a separate video output through a mini-coax cable. The TEC NIR benches have a heatsink and additional electrical connections for both temperature sensor and power for the Peltier cooling.
