55-261 30 x 30 x 9.5 mm; Float Glass; Near-IR (NIR) Reflective Gold Grating; 1200 Grooves/mm Bare Gold
This optical element is a reflective grating, sourced from the renowned vendor Edmund Optics. It is a 30 x 30 x 9.5 mm rectangular grating, made from float glass, a type of soda lime glass known for its excellent optical clarity.
The grating features a near-infrared (NIR) reflective coating, specifically designed for the 750 nm wavelength range. The coating is a bare gold modification, which provides high reflectivity and durability. The grating has 1200 grooves per millimeter, offering a high resolution and precision.
The physical data of the grating includes a blaze wavelength of 750 nm, a blaze angle of 26.73 degrees, and an orientation vector of (1, 0, 0). The grating side is the front, and the order is -1. The grating is in stock and available for immediate purchase, as indicated by its valid weblink status.
This grating is ideal for applications that require high-precision NIR spectral dispersion, such as spectroscopy, beam steering, and optical interferometry. Its robust construction and high-quality coating ensure reliable performance and long-term durability.
