This is a GR13-0310 Near-IR Ruled Reflective Diffraction Grating, a high-quality optical component sourced from Thorlabs. The grating, which is 12.7 mm in width and height and 6 mm in depth, is made of soda lime glass, a material known for its excellent optical properties and durability.
The grating features 300 grooves per millimeter, providing a high level of dispersion (3.3) that can effectively separate different wavelengths of light. The blaze wavelength is 1000 nm, and the blaze angle is 8.6 degrees, which contributes to the grating's high efficiency.
The grating is coated on the front side with a specific coating (tho gr13-0310), which enhances its performance in the near-infrared region. The grating is designed to be used in the first order (-1), and it is intended for use on the front side.
