KPX028-C 6.35 mm Dia. x 75.6 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX028-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 6.35 mm and a thickness at the edge of 3 mm. The center thickness is slightly more at 3.129 mm. The effective focal length (EFL) of the lens is 75.6 mm, which is the distance over which the lens will focus a collimated beam of light to a spot. The back focal length (BFL) is 73.53 mm, which is the distance from the back surface of the lens to the focal point. The lens does not have an inner radius.
The KPX028-C lens features a coating of MgF2 on both the front and back surfaces. This coating is designed to reduce reflection and increase 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. For more detailed information, please refer to the vendor's website.
