SPX062AR.4 25.4 mm Dia. x 75.0 mm FL; AR coated; Plano-Convex Lens AR 230-266nm
The SPX062AR.4 is a Plano-Convex Lens, a type of spherical lens, manufactured by MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 75.0 mm, making it suitable for a wide range of optical applications. The lens is made from fused sil mal-1965, a material known for its excellent optical properties.
The lens features an Anti-Reflective (AR) coating on both the front and back surfaces. This coating, specifically the new AR-4 fromfigure, is designed to minimize reflection and increase transmission in the 230-266nm wavelength range. The coating ensures optimal performance in high-energy applications, reducing losses due to surface reflections.
The lens has a center thickness of 5.408 mm and an edge thickness of 3 mm. The inner radius is zero, indicating a flat surface on the non-curved side of the lens. The effective focal length (EFL) is 75 mm, and the back focal length (BFL) is 71.3 mm. The radius of curvature (R1) is 34.506 mm.
