This optical element is a reflective grating, sourced from the renowned vendor Edmund Optics. It is a 30 x 30 x 9.5 mm float glass grating, with a square base shape and a bare aluminum coating on the front surface. The grating has 600 grooves per millimeter, making it a high-resolution component suitable for a wide range of applications.
The grating is designed to operate at a wavelength of 588 nm, and it features a blaze wavelength of 400 nm. The blaze angle is 6.88 degrees, which contributes to its high efficiency. The orientation vector is (1, 0, 0), indicating that the grooves are parallel to the x-axis. The grating order is -1, and the grating side is the front side.
