The 48-757-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 600-1050nm. The lens features a front and back coating of edm nir-i std curve, which is Edmund Optics' standard curve for NIR applications.
The lens has a thickness of 1.0mm at the edge and 4.6mm at the center. The effective focal length (EFL) is 20.0mm, and the radius of curvature (R1) is 15.7mm. The back focal length (BFL) is 17.42mm, and the lens does not have an inner or outer radius. The lens is made of n-sf11 schott, a material known for its excellent optical properties in the NIR spectrum.
The lens's geometry and material make it suitable for a wide range of NIR applications. The edm nir-i std curve coating ensures high transmission and low reflection in the NIR range, making it ideal for use in systems where minimal signal loss is crucial. The Plano-Convex design allows for efficient light collection and focusing, making it a versatile choice for various NIR applications.
