Compact ROCK VIS-NIR

Compact high throughput and robust spectrometer modules for OEM integration

The compact ROCK VIS-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 of 0.2 (f/2.5) nearly on-axis beam geometry in the optical bench.

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