ROCK Spectrometers
4 times better sensitivity!
The ROCK platform is a series of industrial grade, pre-configured OEM spectrometers that provide:
- High optical throughput
- Symmetrical peak shapes
- Adaptation flexibility for customer specific detectors and electronics
- Robust, athermal design
See the configurations options here: ROCK VIS, ROCK VIS-NIR, ROCK NIR, ROCK SW-NIR and ROCK XNIR.
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
- Biophotonics and pharmaceuticals
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 %.
