SLB-20-60PM 20.0 mm Dia. x 60.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-20-60PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 20.0 mm and a focal length of 60.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The curvature of the convex side is defined by a radius of 31.14 mm, and the lens has an edge thickness of 2.0 mm and a center thickness of 3.6 mm. The Effective Focal Length (EFL) of the lens is 60.0 mm, and the Back Focal Length (BFL) is 57.6 mm.
The SLB-20-60PM is coated with Opt M on both the front and back surfaces. This coating enhances the lens's performance in the 400-700nm wavelength range, providing improved transmission and reduced reflection.
