The KPX013-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 at a wavelength of 589 nm.
The lens has a diameter of 6.35 mm and a thickness at the edge of 3 mm. The center thickness is slightly more, measuring 3.819 mm. The effective focal length (EFL) of the lens is 12.7 mm, and the radius of curvature (R1) is 6.563 mm. The back focal length (BFL) is 10.18 mm, and the inner radius is 0 mm.
The KPX013-C is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with MgF2, a common anti-reflective coating, on both the front and back surfaces. This coating enhances the lens's performance in the 400-700 nm range, reducing surface reflections and increasing transmission.
