KPX178-C 50.8 mm Dia. x 62.9 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm

The KPX178-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, is designed for use in the visible light spectrum, specifically optimized for the wavelength of 589 nm.

The lens has a diameter of 50.8 mm and a thickness at the edge of 3 mm. The center thickness is 15.221 mm, providing a substantial depth for light to pass through. The effective focal length (EFL) of the lens is 62.9 mm, determined by the curvature of the lens, which is 32.507 mm for the first surface (R1). The back focal length (BFL) is 52.86 mm, and the lens does not have an inner radius.

The KPX178-C lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This lens is coated with MgF2, a broadband anti-reflection coating that reduces reflection and increases transmission in the spectral region from 400 to 700 nm.

This lens is available for purchase directly from the vendor's website, and the link provided indicates that it is currently in stock. With its impressive specifications and high-quality construction, the KPX178-C is an excellent choice for a wide range of optical applications.
