SLB-10B-30NM 10.0 mm Dia. x -29.7 mm FL; Coated; Double-Concave Lens 400-700nm
OptoSigma presents the SLB-10B-30NM, a double-concave lens with a 10.0 mm diameter and a focal length of -29.7 mm. This lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide array of optical applications.
The lens is constructed from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The base shape of the lens is circular, and it features a spherical geometry with a center thickness of 2mm and an edge thickness of 2.8mm. The inner and outer radii are both 0mm, and the back focal length is -30.3mm.
The SLB-10B-30NM is coated with Opt M on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
