Product Presentation:
Transmission gratings from Ibsen are produced by holographic/lithographic stepper technology in 100% dielectric materials. This lead to unbeatable thermal and environmental stabiligy, with no polymers, epoxies, gelatins, or metals in the optical path nor in the grating whatsoever. Advanced etching technology ensures the highest diffraction efficiency and lowest PDL. Ibsen’s fused silica transmission gratings are the ideal choice for applications ranging from high-power lasers to telecom devices and compact spectrometers.
