561-6502 50.8 mm Dia. x 127 mm FL Plano-Convex Lens AR 10600nm

This 561-6502 optical lens, sourced from EKSMA Optics, is a Spherical Lens of the Plano-Convex subtype. The lens has a base shape of Circular, with a diameter of 50.8 mm and a thickness edge of 2.5 mm. The effective focal length (EFL) of the lens is 127 mm, and the radius of curvature (R1) is 177.8 mm. The lens does not have an inner radius, and the outer radius is also 0.

The lens is made of Zinc Selenide (ZnSe) material, identified as 'znse marple-1964' in the Material ID. It is designed to operate at a wavelength of 10600nm. The lens features Anti-Reflective (AR) coating on both the front and back surfaces, specifically 'eks znse ar 10600'. This coating enhances the lens's performance by reducing reflection and increasing transmission at the specified wavelength.
