The KPX022-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 589 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 6.35 mm and a thickness at the edge of 3 mm. The center thickness is slightly more at 3.258 mm. The effective focal length (EFL) of the lens is 38.1 mm, which is the distance over which the lens will focus a collimated beam of light to a spot. The front surface radius of curvature (R1) is 19.69 mm, and the back focal length (BFL) is 35.95 mm. The lens does not have an inner radius.
The KPX022-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 coating is applied using the new mgf2bk7fromfigur process, ensuring high-quality and consistent results.
