High throughput and robust spectrometer modules for OEM integration

The ROCK SW-NIR spectrometers offer the market’s highest throughput industrial grade spectrometers. These benefits are accomplished by our highly efficient in-house manufactured transmission gratings and a high numerical aperture 0.22 (f/2.2) nearly on-axis beam geometry in the optical bench.

The ROCK SW-NIR spectrometers enable better sensitivity and/or lower optical light input power than traditional spectrometers.
