SPX025AR.4 25.4 mm Dia. x 150 mm FL; AR coated; Plano-Convex Lens AR 230-266nm

The SPX025AR.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 150 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 reflection and improving overall system efficiency.

The geometry of the lens is carefully designed with a thickness of 3 mm at the edge and 4.181 mm at the center. The inner radius is 0, and the radius of curvature (R1) is 68.85 mm. The back focal length (BFL) is 147.13 mm, and the effective focal length (EFL) is 150 mm.
