The KPX108-C is a Plano-Convex lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens, with a base shape of a circle, is designed for use in the visible light spectrum, specifically optimized for a wavelength of 546.1 nm.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is slightly more, measuring 3.693 mm. The effective focal length (EFL) of this lens is 225 mm, and the radius of curvature (R1) is 116.712 mm. The back focal length (BFL) is 222.57 mm, and the inner radius is 0 mm.
The KPX108-C is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with MgF2, a broadband antireflection coating that reduces surface reflections and increases transmission in the spectral region from 400 to 700 nm.
