This is a 33009FL01-330R Float Glass Plane Ruled Diffraction Grating, sourced from the renowned optical components vendor, MKS/Newport. The grating, which is available for purchase directly from their website, is currently in stock.
The grating is a Blazed Ruled Reflective type, with a rectangular base shape and a size of 25 x 25 x 6 mm. The material used for the grating is soda lime ru clear, a common choice for optical elements due to its excellent transparency and durability.
The grating is designed to operate at a wavelength of 588 nm. It features a coating on the front side, specifically the nwr 53-330r-1264-1p, which enhances its performance and durability.
The physical data of the grating includes a blaze wavelength of 400 nm, 1200 grooves per millimeter, a blaze angle of 14 degrees, and an orientation vector of (1, 0, 0). The grating is designed to operate in the first order, and the grating side is the front.
