KPX085-C 25.4 mm Dia. x 62.9 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX085-C is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a base shape of a circle, is designed for use in the visible light spectrum, specifically at a wavelength of 589 nm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is 5.584 mm, and the effective focal length (EFL) is 62.9 mm. The radius of curvature (R1) is 32.507 mm, and the back focal length (BFL) is 59.21 mm. The lens does not have an inner radius.
The KPX085-C is coated with MgF2, a common anti-reflective coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission in the spectral range of 400-700 nm. The lens is currently in stock and available for purchase, as indicated by its valid weblink status.
