45-485-INK 12.0mm Dia. x 42.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-485-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths 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 enhancing the overall transmission of light through the lens.
The lens has a thickness of 1.85mm at the edge and 2.7mm at the center, with an effective focal length (EFL) of 42.0mm. The radius of curvature for the first surface (R1) is 21.71mm, and the back focal length (BFL) is 40.22mm. The lens does not have an inner or outer radius, indicating a uniform curvature across its surface.
This lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The material is well-suited for use in a wide range of applications, including imaging, beam shaping, and laser systems.
