45-501-INK 20.0mm Dia. x 50.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-501-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front thickness of 1.22mm and a center thickness of 3.23mm, making it a suitable choice for various optical applications.
The lens's effective focal length (EFL) is 50mm, and its front surface has a radius of curvature of 25.84mm. The back focal length (BFL) of the lens is 47.87mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
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 by reducing surface reflections and increasing transmission.
