ROCK Spectrometers
4 times better sensitivity!
The ROCK platform is a series of inustrial grade, pre-configured OEM spectrometers that provide:
- High optical throughput
- Symmetrical peak shapes
- Adaption flexibility for customer specific detectors and electronics
- Robust, athermal design
See the configurations here: ROCK VIS, ROCK VIS-NIR, ROCK SW-NIR, ROCK NIR and ROCK XNIR.
If you have trouble getting enough light for your spectroscopy system, a ROCK sectrometer 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
- Biophotonics
On our application pages you can find help to identify which of our spectrometer platforms 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) whereas typical Czerny-Turner configurations are limited to NA of 0.07 to 0.11 (f-number of 4.5 – 7.1).
Furthermore, the ROCK spectrometers use transmission gratings with efficiency in the 70 – 90 % range, whereas typical blazed reflection gratings are limited to 30 – 60 %.
