This is a 43-746 reflective diffraction grating, sourced from the reputable vendor, Edmund Optics. The grating, which is 12.7 x 12.7 x 6 mm in size, is made of soda lime float glass, a common material in optical applications due to its excellent clarity and durability.
The grating features 600 grooves per millimeter, making it a high-density grating. The blaze wavelength is 1250 nm, and the blaze angle is 22.02 degrees, which is optimal for applications that require high efficiency and low stray light. The grating's orientation vector is along the x-axis, and it operates in the -1st order.
The grating's coating is bare aluminum, which provides high reflectivity in the ultraviolet and visible regions of the spectrum. This coating is often used in applications such as spectroscopy, interferometry, and beam steering.
