（联系我时，请说明是在来宝网上看到的，谢谢！）Transmission gratings operateto angularly disperse incident light into a spectrum. LightSmyth’s transmissiongratings utilize state-of-the-art design and precise lithographic wafer-scalefabrication to deliver record-breaking optical performance combined with lowcost, providing your optical systems with a powerful competitive edge. Thesegratings provide the world’s best combination of highest diffractionefficiency, low PDL and highly competitive pricing.
Advantages:
Exceptional diffraction efficiency
Ultra-low polarization-dependent loss
Special design for broad passband and low angular sensitivity
Uses only fused silica and highly robust dielectric materials
No polymers or organics are used; Telcordia-qualified
Each grating is a master; ultra-low scatter
Highly competitive pricing
Applications:
Optical telecommunications (ROADM, WSS, WDM MUX/DEMUX)
Pulse compression of pico- and femto-second pulses
High power lasers
Spectral beam combining
Remote optical sensors and spectroscopy
