This 561-6254 optical lens, sourced from EKSMA Optics, is a Plano-Convex Spherical Lens with a diameter of 25.4 mm and a focal length of 101.6 mm. The lens is made of Zinc Selenide (ZnSe) material, specifically the ZnSe Marple-1964 variant, which is known for its excellent optical properties.
The lens features an Anti-Reflective (AR) coating on both the front and back surfaces, designed to minimize reflection and increase transmission at a wavelength of 10600nm. This coating enhances the lens's performance in infrared applications.
The lens has a thickness of 2.5 mm at the edge, and its geometry is defined by a radius of curvature (R1) of 142.24 mm on the convex side. The lens does not have an inner radius (R2), and the outer radius (R3) is also not specified, indicating that the lens is a simple Plano-Convex design.
