The KPX114AR.33 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a base shape of a circle, has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is slightly more, measuring 3.445 mm. The effective focal length (EFL) of this lens is 350 mm, and the radius of curvature (R1) is 181.552 mm. The back focal length (BFL) is 347.732 mm, and the inner radius is 0 mm.
This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and availability. The wavelength for this lens is 546.1 nm. The lens features a V-coat on both the front and back, which is a type of anti-reflection coating. This coating reduces reflection and increases transmission, making it ideal for use in laser applications, particularly at 1064 nm.
