KPX229-C 76.2 mm Dia. x 200 mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
The KPX229-C is a Plano-Convex lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens, with a base shape of a circle, is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens has a diameter of 76.2mm and a thickness at the edge of 3mm. The center thickness is 10.27mm, providing a solid structure for efficient light transmission. The effective focal length (EFL) of this lens is 200mm, which is a critical specification for determining the lens's focusing power.
The KPX229-C is made from n-BK7 Schott, a high-quality optical glass known for its excellent optical properties. The lens's front and back surfaces are coated with MgF2, a broadband antireflection coating that reduces surface reflections and increases transmission.
The lens's inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 103.36mm on the curved side. The back focal length (BFL) of the lens is 193.22mm.
