Request InfoIbsen Photonics A/SPolarization-independent (PING) telecom gratings from Ibsen are produced by holographic stepper technology in 100-percent dielectric materials. This leads to unbeatable thermal and environmental stability, with no polymers, epoxies, gelatins or metals in the optical path or in the grating. Advanced etching technology ensures highest diffraction efficiency and lowest PDL over a very broad bandwidth. Low angular sensitivity is an added bonus for module design and assembly. BenefitsHigh-diffraction efficiency and low PDL Environmentally and thermally stable Low sensitivity to illumination...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssueCompact SpectrometersThe compact ROCK VIS and VIS-NIR spectrometers from Ibsen Photonics are designed for blood gas analysis.
