50mm Dia x -129.2mm FL Protected Gold Coated, Convex Mirror

Product Details Variety of Diameters and Focal Lengths Available Enhanced Aluminum and Protected Gold Coatings Ideal for Imaging Systems Convex Spherical Mirrors feature a polished plano second surface and convex first surface. Used primarily for increasing an imaging system’s field of view, convex mirrors create a virtual, upright image. Shorter focal lengths provide wider fields of view, while longer focal lengths provide less distortion. Convex Spherical Mirrors with Enhanced Aluminum coatings are ideal for applications in the visible spectrum, while Protected Gold provides excellent reflection throughout the NIR, MWIR, and LWIR spectra. The mirrors are offered in 12, 25, and 50mm diameters, in a variety of wavelength ranges.
