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.

How to Use your Spectrometer

You can couple into your spectrometer both by free space or via fiber.

You also have several options for reading out over a standard interface like USB or SPI with our different electronics options, which you can see here.
