This is a GR13-0605 Rectangular Blazed Ruled Reflective Grating, sourced from the reputable vendor Thorlabs. The grating, which measures 12.7 mm in width and height, and 6 mm in depth, is made of soda lime glass, a material known for its high transparency in the visible spectrum.
The grating features 600 grooves per millimeter, with a blaze wavelength of 500 nm and a blaze angle of 8.6167 degrees. This configuration results in a dispersion of 1.65, making it suitable for applications that require high angular dispersion. The grating is coated on the front side with a specific coating (tho gr13-0605), enhancing its performance in the specified wavelength range.
The grating's physical data indicates that it operates in the first order (order: -1), and the orientation vector is along the x-axis (x: 1, y: 0, z: 0). This orientation ensures efficient light diffraction when the grating is used as intended.
