49-577 12.7 x 12.7 x 3 mm B270 Glass; Transmission Grating; 830 Grooves/mm Uncoated

The 49-577 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 830 grooves per millimeter, a density that allows for high-resolution spectral dispersion. The blaze wavelength is 400 nm, indicating the wavelength at which the grating is most efficient. The blaze angle is 29.9 degrees, a value that significantly influences the grating's efficiency and dispersion characteristics.

The orientation vector of the grating is (1, 0, 0), meaning the grooves are parallel to the x-axis. The order is -1, indicating the diffraction order of the grating. The grating side is 'Back', suggesting that the incident light should be directed 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 might be suitable for applications where the grating's intrinsic properties are sufficient, or where specific coating requirements are not needed.
