KPX040-C 12.7 mm Dia. x 19.0 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm

The KPX040-C is a Plano-Convex lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens is characterized by its circular base shape and is designed for use in the visible light spectrum, specifically at a wavelength of 589 nm.

The lens has a diameter of 12.7 mm and a thickness at the edge of 3 mm, while the center thickness measures 5.33 mm. The effective focal length (EFL) of the lens is 19 mm, and the radius of curvature (R1) is 9.819 mm. The back focal length (BFL) is 15.48 mm, and the inner radius is 0 mm.

The KPX040-C 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 type of anti-reflective coating that reduces surface reflections and increases transmission in the spectral range of 400-700 nm.

This lens is ideal for applications that require a high-quality, broadband anti-reflection coating. Its compact size and robust construction make it suitable for use in various settings, including optical instruments, beam shaping, and imaging systems.
