The 49-579 is a Transmission Grating, a type of optical component that splits and diffracts light into several beams travelling in different directions. This particular grating, sourced from Edmund Optics, boasts a 25 x 25 x 3 mm rectangular base shape, with a thickness of 3 mm and a width and length of 25 mm each. The grating's inner and outer radii are both zero, indicating a flat surface.
The grating features 300 grooves per millimeter, with a blaze wavelength of 400 nm and a blaze angle of 17.5 degrees. The blaze wavelength is the wavelength at which the grating is most efficient, while the blaze angle is the angle at which the grooves are cut into the grating surface. The orientation vector is (1, 0, 0), meaning the grooves are parallel to the y-axis. The grating's order is -1, and it is designed to be used from the back side.
The grating is made of B270 Schott glass, a high-quality borosilicate glass known for its excellent optical properties and durability. The grating is uncoated, meaning it does not have any additional layers of material applied to its surface to alter its optical properties.
The grating is designed to operate at a wavelength of 588 nm. It is currently in stock and available for purchase, as indicated by its valid weblink status. For more information, users can refer to the provided weblink.
