ROCK spectrometer

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 %.

Which spectrometer to use?

Do you need to evaluate a spectrometer for your next project?
We understand that it can be hard to judge the performance of a spectrometer just from the data sheet. Therefore, we offer a time limited loan of a demo unit to customers that meet certain criteria.
