The SLB-25-220PIR2 is a Plano-Convex Spherical Lens, 25.0 mm in diameter and 220.0 mm in focal length, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a Plano-Convex geometry, with a center thickness of 2.7 mm and an edge thickness of 2 mm. The front and back surfaces of the lens are coated with Opt IR2, a broadband anti-reflection coating designed for the 750-1550nm wavelength range. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.
The lens's design is circular, and it has an inner radius of 0 mm and an outer radius of 0 mm. The effective focal length (EFL) is 220.2 mm, and the back focal length (BFL) is 218.2 mm. The radius of curvature for the first surface (R1) is 114.18 mm.
