SPX028AR.3 25.4 mm Dia. x 200 mm FL; AR coated; Plano-Convex Lens AR 355nm
The SPX028AR.3 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-3 fromfigure, is designed to minimize reflections and increase transmission at the specified wavelength of 589 nm. The edge thickness of the lens is 3 mm, while the center thickness is 3.883 mm. The back focal length (BFL) is 197.33 mm, and the effective focal length (EFL) is the same as the focal length at 200 mm.
The lens is available from the vendor's website, and the link provided indicates that it is currently in stock. This makes it an ideal choice for users who need a high-quality, readily available optical component for their systems.
