KPX211-C 50.8 mm Dia. x 500 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX211-C is a Plano-Convex lens, a type of spherical lens, sourced from the renowned optical component vendor, MKS/Newport. This lens, with a base shape of a circle, has a diameter of 50.8 mm and a thickness at the edge of 3 mm. The center thickness is 4.251 mm, and the effective focal length (EFL) is 500 mm. The lens's front surface has a radius of curvature (R1) of 258.4 mm, and the back focal length (BFL) is 497.19 mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and availability.
The KPX211-C lens is designed for use in the wavelength range of 400-700 nm, covering the visible light spectrum. It is coated with MgF2, a broadband antireflection coating that reduces surface reflections and increases transmission. The MgF2 coating is applied to both the front and back surfaces of the lens. This lens is currently in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website at https://www.newport.com/f/mgf2-n-bk7-plano-convex-lenses.
