ROCK Spectrometers

4 times better sensitivity !

ROCK%20NIR%20Spectrometer

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

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

So, if you have trouble getting enough light for your spectroscopy system a ROCK spectrometer could be your answer.

Applications

Our spectrometers are well suited as the spectral engine in your analytical instrument for a wealth of applications in:

  • Health care and life science
  • Food and agriculture
  • Light measurement
  • Semiconductor manufacturing
  • Security
  • Bio-photonics and pharmaceuticals

On our applications pages you can find help to identify which of our spectrometer platforms that best suits your needs.

High throughput by 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.

The on-axis geometry of the ROCK spectrometers enables a much larger acceptance angle for the input beam than the Czerny-Turner configuration and thereby a much higher amount of coupled light. The numerical aperture (NA) of the ROCK spectrometers are 0.22 (f-number of 2.2) wheras typical Czerny-Turner configurations are limited to NA of 0.11 to 0.16 (f-number of 3.5 - 4.5).

Furthermore, the ROCK spectrometer uses transmission grating with efficiencies in the 70 - 90 % whereas typical blazed reflection gratings are limited to 30 - 60 %.

You can read much more about the benefits of transmission grating based spectrometers here.
