The 49-581 is a Transmission Grating, a type of optical component used to diffract light into several beams, with the grating acting as a diffraction grating. Sourced from Edmund Optics, this grating has a base shape of a rectangle, with dimensions of 25 x 25 x 3 mm. The grating's physical data includes 830 grooves per millimeter, a blaze wavelength of 400 nm, and a blaze angle of 29.9 degrees.
The orientation vector of this grating is (1, 0, 0), indicating that the grooves are parallel to the x-axis. The grating is designed to operate in the first order, and the grating side is the back. The material of this grating is B270 glass, a type of borosilicate glass known for its excellent optical transmission and chemical resistance.
This grating is uncoated, meaning it does not have any additional layers of material applied to enhance its optical properties. The catalog number for this item is 49-581, and it is currently in stock. For more information, users can visit the provided weblink.
