45-505-INK 25.0mm Dia. x 30.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-505-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm.
The lens has a front (plano) side that is flat and a back (convex) side that is curved. The back side has a radius of curvature (R1) of 15.5mm. The lens's thickness varies from 1.73mm at the edge to 8.06mm at the center. The effective focal length (EFL) of the lens is 30.0mm, and the back focal length (BFL) is 24.69mm.
The lens is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The lens is coated with 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 reflection and increasing transmission.
