The 45-509-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, contributing to its overall thickness of 2.07mm at the edge and 4.7mm at the center.
The lens's effective focal length (EFL) is 60mm, and its radius of curvature (R1) is 31.01mm. The back focal length (BFL) is 56.9mm, and the lens does not have an inner or outer radius. The lens is made of N-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties and wide transparency range.
The lens is coated with edm visnir0sp2002000 on both the front and back sides. This coating is designed for the visible to near-infrared spectrum, enhancing the lens's performance in this range. The lens is currently in stock and available for immediate purchase.
