KPX579-C 25.4 mm Dia. x 38.1 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm

The KPX579-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 at a wavelength of 546.1 nm.

The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The center thickness is slightly more, measuring 7.64 mm. The effective focal length (EFL) of the lens is 38.1 mm, making it suitable for a variety of optical applications.

The KPX579-C features an inner radius of 0 mm, indicating a plano surface on one side. The other side has a radius of curvature of 19.69 mm. The back focal length (BFL) of the lens is 33.06 mm.

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

The coating on both the front and back surfaces of the lens is new MgF2 from figur, ensuring high-quality performance and durability. The KPX579-C is currently in stock and available for immediate purchase through the Newport website, as indicated by its valid weblink status.
