KPX208AR.33 50.8 mm Dia. x 400 mm FL; V-Coat; Plano-Convex Lens V-Coat 1064nm
The KPX208AR.33 is a Plano-Convex lens, sourced from MKS/Newport, with a diameter of 50.8 mm and a focal length of 400 mm. This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and availability. The lens has a front and back coating of New AR-33, a broadband anti-reflective coating designed for high performance across a wide range of wavelengths, specifically optimized for 1064 nm.
The lens geometry includes an edge thickness of 3 mm and a center thickness of 4.566 mm. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) is 206.72 mm, and the back focal length (BFL) is 396.98 mm. The effective focal length (EFL) is the same as the focal length, at 400 mm.
