KPX582-C 25.4 mm Dia. x 50.2 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX582-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 optimized for a wavelength of 546.1 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 6.32 mm, providing a decent depth to the lens. The effective focal length (EFL) of the lens is 50.2 mm, which is the distance from the lens's center to the focal point. The front radius of curvature (R1) is 25.94 mm, and the back focal length (BFL) is 46.03 mm. The lens does not have an inner radius.
The KPX582-C lens features a coating of MgF2 (Magnesium Fluoride) on both the front and back surfaces. This coating is known for its excellent optical properties, including a high transmission rate in the visible light spectrum (400-700 nm) and a durability that provides resistance to environmental factors. The MgF2 coating also reduces reflection, increasing the amount of light transmitted through the lens.
According to the vendor, the KPX582-C lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website linked below.
