The KPX552-C is a Plano-Convex lens, a type of spherical lens, sourced from 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 546.1 nm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens has a diameter of 12.7 mm and a thickness at the edge of 3 mm. The center thickness is slightly more at 3.62 mm. The effective focal length (EFL) of the lens is 62.9 mm, which is the distance from the lens's center to the focal point. The front radius of curvature (R1) is 32.5 mm, and the back focal length (BFL) is 60.5 mm. The lens does not have an inner radius.
The KPX552-C lens features a coating of MgF2 on both the front and back surfaces. This coating, often used in high-performance optical systems, reduces reflection and increases transmission in the spectral range of 400-700 nm. The lens is currently in stock and available for purchase, as indicated by its valid web link status.
