Image Description

High Efficiency Transmission Grating T-1500-930 Series T-1500-930 series lithographically patterned diffraction transmission grating is designed to be used in demanding industrial applications. It is characterized by high efficiency, low polarization sensitivity and high power handling. Gratings produced by LightSmyth undergo extensive quality assurance, have proven reliability track record and competitively priced. The polarization independent transmission grating has 1500.38 lines/ mm and designed to operate near 930 nm central wavelength at 44.2 angle of incidence (AOI). Extended wavelength range performance and angular sensitivity information is provided below. 100 100 90 95 80 90 70 S 85 S pol P 60 P pol Average 80 50 0.88 0.93 0.98 35 40 45 50 55 Wavelength (m) AOI (deg) Typical absolute diffraction efficiency at AOI 44.2 * Diffraction efficiency at 930 nm as a function of AOI * Extended operational range: The grating may operate over broader wavelength range provided that suitable anti- reflective coating and angle of incidence is used. The plot below shows simulated performance* over extended range assuming fixed input angle (designed Littrow angle of 44.2), not accounting for AR coating losses.

Transmission Typical Optical Layout Grating The transmission grating is designed to operate in Littrow configuration, where the angle of incidence and diffraction are the same for the central operational wavelength. Light is dispersed in the plane perpendicular to the grooves. Incidence Angle Diraction Angle LightSmyth Technologies www.LightSmyth.com Tel + 1-541-431-0026 2017 LightSmyth Technologies.
