This is a Plano-Convex lens, type of spherical lens, sourced from Edmund Optics. The lens has a circular base shape with a diameter of 50.0mm and a thickness of 2.0mm at the edge, while the center thickness measures 5.07mm. The effective focal length (EFL) of the lens is 200.0mm, and the radius of curvature (R1) is 103.36mm. The back focal length (BFL) is 196.66mm, and the inner and outer radii are both 0mm.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The lens is coated with YAG-BBAR, a type of coating that enhances its performance in the wavelength range of 500-1100nm. This coating is applied on both the front and back surfaces of the lens, ensuring optimal light transmission and minimal reflection within the specified wavelength range.
