II-VI LightSmyth™ Transmission Diffraction Gratings
• High Di£ raction E¤ ciency (>94% Absolute) and Low Scatter
• Polarization Independent and Single Polarization Optimized Gratings
• Robust Inorganic Materials for Superior Power Handling and Reliability
II-VI LightSmyth™ Transmission Di¢ raction 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 di¢ raction e¬ ciency of ®94%, minimizing optical losses
when used in multi-pass con gurations. Gratings designed for near infrared (NIR) wavelengths between
800 - 1800 nm are available with all featuring a precision line density uniformity of 0,001 lines/mm. II-VI
LightSmyth™ Transmission Di¢ raction 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 e¢ ects on performance. Please contact us for
custom sizes or OEM requirements.

Adjustable Grating Mounts
• Mount up to 60 mm Tall Di£ raction Gratings
• Easy Adjustment via Side Locking Screws
• Designed for Integration into 25,4 mm Diameter Optic Mounts
Adjustable Grating Mounts are designed to hold di¢ raction gratings without damaging their sensitive
grating surface. Featuring a 3-point mounting style with spring and metal contacts, these mounts
provide adequate clamping pressure while allowing for easy adjustment via side locking screws.
A 25,4 mm diameter extension on the rear of the mount allows for integration into Edmund Optics’
kinematic and xed mirror mounts. Adjustable Grating Mounts can be adjusted to accommodate a
range of grating sizes, up to 60 mm in height.
Note: Kinematic mount, mounting plate, post, and post holder sold separately.
