Coherent LightSmyth 1040nm, 1000 Grooves/mm, 31.8 x 24.8mm Transmission Diffraction Grating

Product Details High Diffraction Efficiency (≥90% Absolute) and Low Scatter Polarization Independent and Single Polarization Optimized Gratings Robust Inorganic Materials for Superior Power Handling and Reliability Designs for NIR Wavelengths between 800 – 1800nm Coherent LightSmyth Transmission Diffraction Gratings are manufactured through a precision lithographic wafer-scale fabrication process and provide excellent optical performance, low polarization sensitivity, and low scatter. These gratings have a high diffraction efficiency of ≥90%, minimizing optical losses when used in multi-pass configurations. Gratings designed for near infrared (NIR) wavelengths between 800 – 1800nm are available with all featuring a precision line density uniformity of 0.001 lines/mm. Coherent LightSmyth Transmission Diffraction Gratings are used in demanding applications including Spectral Beam Combining (SBC), LiDAR, optical telecommunications, pulse compression of pico- and femtosecond pulses, and spectroscopy. These gratings contain no organic materials and can be used with high power lasers and in environments up to 500 °C with no effects on performance.
