This is a 43-744 reflective diffraction grating, sourced from the renowned optical components vendor, Edmund Optics. The grating, which is 12.7 mm in width and length, is made of soda lime float glass, a material known for its excellent optical clarity. The grating has a thickness of 6 mm, providing robustness and stability.
The diffraction grating features 600 grooves per millimeter, with a blaze wavelength of 750 nm. The blaze angle is 13 degrees, optimizing the grating for use in the first order of diffraction. The grating's orientation vector is along the x-axis, and it is designed to be used with the front side coated.
The coating on the front side of the grating is edm diel bare al oap, a bare aluminum coating that provides high reflectivity. The grating is currently in stock and available for immediate purchase.
