The 45-507-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 (VIS-NIR) spectrum, specifically between 400-1000nm. The lens has a front thickness of 1.39mm and a center thickness of 5.6mm, making it suitable for a variety of optical applications.
The lens's effective focal length (EFL) is 40mm, and its front surface has a radius of curvature (R1) of 20.67mm. The back focal length (BFL) is 36.31mm, and the lens does not have an inner or outer radius. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.
The 45-507-INK 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 VIS-NIR spectrum by reducing reflection and increasing transmission.
