SPX062AR.2 25.4 mm Dia. x 75.0 mm FL; AR coated; Plano-Convex Lens AR 532nm
The SPX062AR.2 is a high-energy plano-convex lens, designed and manufactured by MKS/Newport. This lens, with a diameter of 25.4 mm, is specifically engineered for use with a wavelength of 546.1 nm. The lens is made from fused sil mal-1965, a material known for its excellent optical properties.
The lens features a plano-convex geometry, with a center thickness of 5.408 mm and an edge thickness of 3 mm. The radius of curvature for the convex surface is 34.506 mm, and the back focal length is 71.3 mm. The effective focal length of the lens is 75 mm.
The lens is coated with a new AR-2 coating on both the front and back surfaces. This anti-reflective coating is designed to minimize losses due to reflection, thereby enhancing the efficiency of the optical system in which the lens is used. The coating is specifically optimized for the 532 nm wavelength.
