It’s small! It’s sensitive! It’s the grating!


Ibsen is the industry leader in this field, as we are able to make gratings more precisely than anybody else. If you magnify our gratings to the size of a football field, the precision of our grating lines would correspond to a thin blade of grass. Based on these transmission gratings, with the market’s highest efficiency, we offer compact OEM spectrometers. They all have a proven high throughput, verified unit-to-unit repeatability, and provide a flat spectral response. Our decades of experience in delivering transmission gratings have taught us to master the technique to produce gratings for compact and handheld devices.

Compact Spectrometers for Blood Gas Analysis and OCT System Integration


Ibsen Photonics Launches Compact Spectrometer for Blood Gas Analysis and OCT (Optical Coherence Tomography) System Integration Farum, January 23, 2023 Ibsen Photonics, a global leader in fused silica transmission gratings and spectrometer modules, today announced the launch of the compact ROCK VIS and VIS-NIR line and compact EAGLE OCT OEM spectrometers. The compact ROCK VIS and VIS-NIR spectrometer have a form factor of 75 mm x 50 mm x 30 mm, high throughput, and low stray light. The ROCK spectrometers typically enable 4 times higher optical throughput than traditional spectrometers due to a low f-number of f/2.5 and the use

PEBBLE NIR spectrometer

Ibsen Photonics Launches PEBBLE NIR – Ultra Compact Spectrometer Modules for Instrument Integrators


For immediate release Press Release – Farum, January 18, 2022 Ibsen Photonics (, the global leader in fused silica transmission gratings and industrial grade spectrometer modules, today announced the ultra compact PEBBLE NIR OEM spectrometer. Ibsen’s PEBBLE NIR spectrometer is an addition to the PEBBLE platform of ultra compact spectrometers with a form factor of only 23 mm x 21 mm x 8 mm, high resolution, and sensitivity, as well as environmental ruggedness. PEBBLE NIR is based on the same proven diffraction grating technology used in all other Ibsen spectrometers. This ensures that PEBBLE can be manufactured in high quantities
