ROCK NIR

High throughput and robust spectrometer modules for OEM integration

The ROCK 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 0.22 (f/2.2) nearly on-axis beam geometry in the optical bench.

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

ROCK NIR 900 – 1700 nm

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.

Which spectrometer to use?

Do you need to evaluate a spectrometer for your next project?
We understand that it can be hard to judge the performance of a spectrometer just from the data sheet. Therefore, we offer a time limited loan of a demo unit to customers that meet certain criteria.
