This optical component is a reflective grating, sourced from Edmund Optics, measuring 25 x 25 x 6 mm. The grating is made of soda lime ru clear float glass, a common material in optical applications due to its excellent transparency and durability.
The grating features 300 grooves per millimeter, with a blaze wavelength of 760 nm, making it suitable for applications in the near-infrared spectrum. The blaze angle is 6.5 degrees, which contributes to its high efficiency in reflecting light at the specified blaze wavelength.
The coating on the front surface is edm diel bare al oap, a bare aluminum coating that provides high reflectivity. This coating is applied to enhance the grating's performance, particularly in reflection applications.
The grating's geometry is rectangular, with no inner or outer radius, making it a flat, rectangular structure. The grating side is the front side, and the order is -1, indicating the grating's diffraction order.
