SLB-80B-500PM 80.0 mm Dia. x 501.0 mm FL; Coated; Double-Convex Lens 400-700nm
OptoSigma presents the SLB-80B-500PM, a high-quality double-convex lens designed for use within the wavelength range of 400-700nm. This lens boasts a diameter of 80.0 mm and a focal length of 501.0 mm, making it suitable for a wide range of optical applications.
The lens is made from the renowned n-BK7 material, produced by Schott, ensuring excellent optical performance and durability. The base shape of the lens is circular, and it features a spherical geometry with specific radii for both the front and back surfaces (R1: 519, R2: -519). The lens has an effective focal length (EFL) of 501 mm, a central thickness of 6.1 mm, and an edge thickness of 3 mm.
The SLB-80B-500PM comes with an antireflection coating on both the front and back surfaces, optimized for a central wavelength of 546.1 nm. This coating reduces surface reflections, enhancing the overall transmission of light through the lens and minimizing unwanted optical losses.
