45-489 12.0mm Dia. x 84.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a diameter of 12.0mm and a focal length of 84.0mm, making it suitable for a wide range of applications. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens features a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance in the visible to near-infrared spectrum, which spans from 400 to 1000nm. The coating is designed to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The geometry of the lens includes a thickness of 2.08mm at the edge and 2.5mm at the center. The lens's inner and outer radii are both 0mm, indicating a planar surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 43.43mm, and the back focal length is 82.39mm.
