49-575 12.7 x 12.7 x 3 mm B270 Glass; Transmission Grating; 300 Grooves/mm Uncoated

The 49-575 is a Transmission Grating, a type of optical component that separates incident light into its constituent wavelengths. This particular grating, sourced from Edmund Optics, boasts a size of 12.7 x 12.7 x 3 mm and is made of B270 glass, a material known for its excellent optical properties.

The grating features 300 grooves per millimeter, a characteristic that determines its dispersion capabilities. The blaze wavelength is 400 nm, indicating the wavelength at which the grating is most efficient. The blaze angle is 17.5 degrees, a parameter that significantly influences the grating's efficiency.

The orientation vector is (1, 0, 0), suggesting that the grating's lines are parallel to the x-axis. The order is -1, implying that the grating operates in the first diffraction order. The grating side is 'Back', indicating that the incident light should enter from the back side of the grating.

The grating is uncoated, meaning it does not have any additional layers to enhance its optical properties. This could be beneficial in certain applications where the introduction of a coating might alter the desired optical characteristics.
