SLB-50.8B-150PM 50.8 mm Dia. x 151.2 mm FL; Coated; Double-Convex Lens 400-700nm
OptoSigma presents the SLB-50.8B-150PM, a high-quality double-convex lens with a diameter of 50.8 mm and a focal length of 151.2 mm. This lens is designed for use within the wavelength range of 400-700 nm, making it suitable for a wide array of optical applications.
The lens is made from the renowned material n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This specific lens features a base shape of a circle and a spherical geometry, ensuring optimal light transmission and focus. The front and back surfaces of the lens are coated with Opt M, a broadband antireflection coating that further enhances the lens' performance by reducing surface reflections.
The SLB-50.8B-150PM has an edge thickness of 2.8 mm and a center thickness of 7 mm, contributing to its robust construction. The lens' inner and outer radii are 0 mm, which is indicative of its symmetrical design. The effective focal length (EFL) is 151.2 mm, and the back focal length (BFL) measures 148.9 mm.
