The 45-494-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 catering to wavelengths of 587.6nm.
The lens's geometry is intricately designed, with a thickness at the edge of 1.59mm and a center thickness of 3.0mm. The effective focal length (EFL) is 40mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) is 38.02mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with edm visnir0sp2002000 on both the front and back, a coating specifically designed for VIS-NIR applications, enhancing its performance in this spectrum.
