SPX028AR.4 25.4 mm Dia. x 200 mm FL; AR coated; Plano-Convex Lens AR 230-266nm
The SPX028AR.4 is a Plano-Convex Lens, a type of spherical lens, manufactured by MKS/Newport. This lens has a diameter of 25.4 mm and a focal length of 200 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. This makes the lens ideal for use in high-energy applications where maximum transmission is required.
The lens has a thickness of 3 mm at the edge and 3.883 mm at the center. The back focal length is 197.33 mm, and the inner radius is 0 mm. The lens is designed to be used in air, with an effective focal length (EFL) of 200 mm.
The SPX028AR.4 is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.newport.com/f/ar4-high-energy-plano-convex-lenses.
