45-485 12.0mm Dia. x 42.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-485 is a Plano-Convex lens, a type of spherical lens, with a diameter of 12.0mm and a focal length of 42.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared regions of the spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it suitable for a wide range of applications.
The geometry of the lens includes a thickness of 1.85mm at the edge and 2.7mm at the center. The lens's inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other. The lens's effective focal length (EFL) is 42.0mm, and the back focal length (BFL) is 40.22mm.
