The 45-479-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front ( convex ) radius of 18.61mm and a back focal length of 34.48mm.
The lens's geometry includes a thickness of 1.75mm at the edge and 2.3mm at the center. The effective focal length (EFL) is 36mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens features a VIS-NIR coating, specifically edm visnir0sp2002000, 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.
