ROCK NIR

Home / Products / OEM spectrometers / 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.

Developer’s Kit

The ROCK NIR is offered with a Developer’s Kit for a plug and play experience.

The Developer’s Kit allows you to easily demonstrate the performance of the spectrometer without the need for complex hardware integration or time-consuming programming.

Benefits of transmission grating based spectrometers

The ROCK is a series of high-throughput spectrometers. This is obtained by a unique lens-grating-lens design utilizing Ibsen Photonics’ high dispersion transmission gratings. Furthermore, the spectrometers provide high efficiency and impressive resolution.

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.
