SPX031AR.4 25.4 mm Dia. x 500 mm FL; AR coated; Plano-Convex Lens AR 230-266nm
The SPX031AR.4 is a high-energy plano-convex lens, designed and manufactured by MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of 500 mm, making it suitable for a wide range of applications. The lens is made from fused sil mal-1965, a material known for its excellent optical properties.
The lens features a new AR-4 coating on both the front and back surfaces, designed to enhance its performance in the 230-266 nm wavelength range. This coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system in which the lens is used.
The geometry of the lens is carefully crafted to ensure optimal performance. The edge thickness is 3 mm, while the center thickness is 3.352 mm. The inner radius is 0, and the radius of curvature (R1) is 229.5 mm. The back focal length (BFL) is 497.7 mm, and the effective focal length (EFL) is 500 mm.
The lens is spherical in shape, and its base shape is circular. It is available for purchase through the Newport website, where it is currently listed as in stock. For more detailed information, users are encouraged to visit the provided weblink.
