KPX122-C 25.4 mm Dia. x 850 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX122-C is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 850 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The KPX122-C features a MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission in the spectral range of 400-700 nm. The coating is applied using the new mgf2bk7fromfigur process, ensuring high-quality and durable performance.
The lens has a thickness of 3 mm at the edge and 3.183 mm at the center. The inner radius is 0, indicating a plano surface on the other side of the lens. The effective focal length (EFL) is 850 mm, and the back focal length (BFL) is 847.9 mm. The radius of curvature (R1) is 440.912 mm.
