25.4mm Dia., Gold Coated, Aluminum Substrate Mirror

Product Details Aluminum Substrate Mirrors Ideal for LWIR Laser Applications Aluminum and Gold Coating Options Metal Substrate Mirrors are available with either a protected aluminum or gold coating and are ideal for LWIR (greater than 2000nm) laser applications. Due to the 17.5nm roughness of the diamond turned surface, these mirrors may not be suitable for UV and visible applications that require low scatter. The backs of the mirrors are machined flat and are tapped with 3 holes for easy, accurate mounting. Metal Substrate Mirrors are aluminum substrate, diamond turned metal mirrors. These mirrors are available in five diameters: 25.4, 38.1, 50.8, 76.2, and 101.6mm.
