Ibsen ROCK Spectrometers in the VIS-NIR, XNIR, NIR Configurations

4X better light sensitivity


The ROCK platform is a series of industrial grade, pre-configured OEM spectrometers that provide:


  • High optical throughput
  • Symmetrical peak shapes
  • Adaption flexibility for customer specific detectors and electronics
  • Robust, athermal design

The ROCK spectrometers are based on a transmission geometry with two lenses and a transmission grating in a nearly on-axis beam geometry. This is in contrast to the typical Czerny-Turner design that uses two mirrors and a reflection grating in an off-axis beam geometry.


As a result, the ROCK spectrometers use transmission gratings with efficiency in the 70 – 90 % range, whereas typical blazed reflection gratings are limited to 30 – 60 %. The benefit is if you have trouble getting enough light for your spectroscopy system, a ROCK spectrometer could be your answer.
