43-739 12.7 x 12.7 x 6 mm Float Glass; Square Reflective Ruled Diffraction Grating; 600 Grooves/mm Bare Aluminum

The 43-739 is a reflective diffraction grating, a type of optical component used to separate and recombine light. This particular model, sourced from Edmund Optics, boasts a square shape with dimensions of 12.7 mm in width and length, and a thickness of 6 mm. The grating is made of soda lime float glass, a common material in optical applications due to its excellent optical clarity and durability.

The grating features 600 grooves per millimeter, a high density that allows for precise manipulation of light. The blaze wavelength is 250 nm, indicating the wavelength at which the grating is most efficient. The blaze angle is 4.3 degrees, a measure of the angle at which the grooves are cut into the grating surface. This angle influences the grating's efficiency and the wavelength at which it operates.

The grating's coating is bare aluminum on the front side, providing a reflective surface for the incident light. The orientation vector is (1, 0, 0), meaning the grooves are parallel to the x-axis. The order is -1, indicating the order of the diffracted light. The grating side is front, specifying the side of the grating where the grooves are located.
