This is a 33066FL01-550R 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 geometry that measures 12.5 mm in width, 25 mm in height, and 6 mm in thickness. It does not have an inner or outer radius. The grating is made of soda lime ru clear material, a common choice for its high transparency and durability.
The grating is designed to work with a wavelength of 588 nm. It features a coating on the front side, specifically the nwr 53550r105633641s coating. This coating enhances the grating's performance and durability.
In terms of its physical data, the grating has a blaze wavelength of 1600 nm, 600 grooves, a blaze angle of 28.7 degrees, and an orientation vector of (1, 0, 0). The grating is designed to operate in the first order and is located on the front side.
