This optical element is a reflective ruled diffraction grating, sourced from the renowned vendor Edmund Optics. It is a rectangular grating, with dimensions of 12.5 mm in width, 25 mm in length, and 9.5 mm in thickness. The grating is made of soda lime float glass, which is known for its high transparency and durability.
The grating features 600 grooves per millimeter, with a blaze wavelength of 400 nm. The blaze angle is 6.88 degrees, which is optimal for diffracting light at the specified blaze wavelength. The orientation vector of the grating is along the x-axis, and the order is -1, indicating the diffraction order of the grating.
The grating's coating is bare aluminum on the front side, which provides high reflectivity and durability. The grating is currently in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website, where you can find the product link and its status.
