45-955 2.0mm Dia. x 1.5mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 45-955 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by having one side flat and the other side curved. This particular model, sourced from Edmund Optics, boasts a diameter of 2.0mm and a focal length of 1.5mm. The lens is designed for use within the near-infrared spectrum, specifically between 600 and 1050nm.
The lens is constructed from n-lasf9 Schott, a material known for its excellent optical properties. It features a front and back coating of edm nir-i std curve, which is a standard coating for near-infrared applications. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
The geometry of the lens is also noteworthy. It has an outer radius of 0mm, meaning it is perfectly circular. The edge thickness is 0.32mm, while the center thickness is 0.8mm. The back focal length (BFL) is 1.07mm, and the effective focal length (EFL) is 1.5mm. The lens's inner radius is 0mm, indicating that it is a plano lens on the flat side.
