Tunable filters
Optical channel monitors (OCM)
Wavelength blockers
Mux / Demux
LIDAR
OCT (Optical Coherence Tomography)

Product overview

While we primarily supply PING gratings as OEM gratings, the following gratings, and many other gratings, are available from stock. You can order the gratings via the product links, or request a quotion for these or other customized gratings below.

Polarization Independent Gratings

Polarization independent (PING) telecom gratings from Ibsen are produced by holographic stepper technology in 100% dielectric materials. This leads to unbeatable thermal and environmental stability, 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 over a very broad bandwidth. Low angular sensitivity is an added bonus for module design and assembly.
