63-687 30mm Dia. x 120mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
This is a 30mm diameter, 120mm focal length double-convex lens, specifically designed for the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its valid weblink status.
The lens's geometry is characterized by a thickness of 3.17mm at the edge and 5mm at the center, with a back focal length of 118.34mm. The first and second radii of curvature are 123.17mm and -123.17mm, respectively. The lens is made of n-BK7 Schott material, a common choice for its excellent optical properties and versatility.
The lens features a VIS-NIR coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to enhance the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving transmission.
