ROCK and roll your XNIR


The ROCK XNIR spectrometers from Ibsen offer 2-6 times higher sensitivity than competing technologies for near infrared spectroscopy and are ideal for process control applications due to their compact size and ruggedness. So, maybe your cookie dough ingredients have been tested by an Ibsen ROCK XNIR spectrometer.

The enabling technology for the high performance is our unique transmission gratings. You can read much more about the benefits of transmission grating based spectroscopy in our white paper.


Our ROCK XNIR is based on our ROCK platform of industrial grade, pre-configured OEM spectrometers that provide high throughput, flexibility in detector choice and a rugged and athermal design.

It offers a wavelength range of 1100 to 2100 nm and uses a numerical aperture of 0.22. The ROCK spectrometers are based on a transmission geometry with two lenses and a transmission grating in a nearly on-axis beam geometry. In addition, our transmission gratings have an efficiency in the 70 – 90 % range.

The Benefits of Transmission Grating Based Spectroscopy

In this white paper, Thomas, our VP of Business Development, Sales, and Marketing, has described how compact spectrometers based on transmission gratings can provide important benefits such as a high throughput and flexibility for OEM integrators.
