- 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 %.
