63-829 12mm Dia. x 20mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-829 is a high-quality double-convex lens, designed and manufactured by Edmund Optics. This lens boasts a 12mm diameter and a 20mm focal length, making it suitable for a wide range of applications. The lens is constructed from fused silica, a material known for its excellent optical properties and durability.
The lens features a UV-optimized double-convex design, with radii of curvature of 17.63mm and -17.63mm for the front and back surfaces, respectively. This design results in a high-quality image with minimal distortion and aberration. The lens has an effective focal length of 20mm and a back focal length of 18.44mm, providing flexibility in optical system design.
The 63-829 lens is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible and near-infrared regions of the spectrum, from 400nm to 1000nm. The coating reduces surface reflections, improving transmission and enhancing the overall performance of the lens.
