The 45-493-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically between 400-1000nm.
The lens features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the VIS-NIR range. This coating helps to minimize surface reflections, thereby improving transmission and reducing stray light.
The lens has a thickness of 1.25mm at the edge and 3.18mm at the center. The effective focal length (EFL) is 30mm, and the radius of curvature (R1) is 15.52mm. The back focal length (BFL) is 27.9mm, and the lens has no inner or outer radius, indicating a plano surface on the opposite side of the convex surface.
This lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. It is widely used in various applications, including imaging systems, beam shaping, and collimation.
