SLB-50.8B-100PM 50.8 mm Dia. x 101.5 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-50.8B-100PM is a high-quality spherical lens offered by OptoSigma, designed for use within the wavelength range of 400-700nm. This lens features a base shape of a circle and is constructed with a double-convex geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 50.8mm and a center thickness of 9.3mm, ensuring durability and resistance to deformation. The edge thickness is 3mm, which aids in maintaining the structural integrity of the lens. The effective focal length (EFL) of this lens is 101.5mm, and its back focal length (BFL) is 98.5mm, making it an ideal choice for various optical systems.
The lens is made from the well-known N-BK7 material from Schott, which is known for its excellent optical properties and low auto-fluorescence. The front and back surfaces of the lens are coated with Opt M, a coating that enhances the overall performance of the lens by reducing surface reflections and increasing transmission.
