KPX118-C 25.4 mm Dia. x 500 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX118-C is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a base shape of a circle, has a diameter of 25.4 mm and a thickness at the edge of 3 mm. The thickness at the center is slightly more, measuring 3.312 mm. The effective focal length (EFL) of this lens is 500 mm, and its radius of curvature (R1) is 258.4 mm. The back focal length (BFL) is 497.81 mm, and the inner radius is 0 mm.
This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with MgF2, a common anti-reflective coating, on both the front and back surfaces. This coating enhances the lens's performance in the wavelength range of 400-700 nm.
The lens's coating and material make it suitable for various applications, including but not limited to imaging, beam shaping, and laser systems. The lens is currently in stock and available for purchase through the provided web link.
