(2)P-polarization: incident electric-field vector perpendicular to grating lines.
(1) Gratings will be highly efficient over a larger range of angles please inquire, Pulse compression of pico- and femtosecond pulses Optical telecommunications (ROADM, WSS, WDM mux/demux) No polymers or organics are used Telcordia-qualifiedĮach grating is a master ultralow scatterĮxtremely precise line density (line density uniformity, <0.001 lines/mm) Uses only fused silica and highly robust dielectric materials Special design for broad passband and low angular sensitivity Ultralow polarization-dependent loss (for applicable designs) Unlike reflection diffraction gratings, transmission diffraction gratings may be polarization-independent and can operate at the optimal Littrow angle with conveniently large angular separation between the input and diffracted beam They contain no organic materials and can withstand temperatures of up to 500☌ with no performance degradation.
High-energy pulsed and CW laser systems will benefit from the high optical damage threshold of our diffraction gratings. High diffraction efficiency (95% typical) allows our customers to minimize optical losses in multipass configurations. These gratings offer an attractive combination of excellent optical performance, reliability, and competitive pricing. The product line of transmission gratings by II-VI utilizes state-of-the-art design and precise lithographic wafer-scale fabrication to deliver record-breaking optical performance combined with low cost, providing your optical systems with a powerful competitive edge. Transmission gratings operate to angularly disperse incident light into a spectrum.
