SLB-07-50PM 7.0 mm Dia. x 50.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-07-50PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 7.0 mm and a focal length of 50.0 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 transparency 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 25.95 mm. The lens has an effective focal length (EFL) of 50 mm, which is the distance from the lens's principal point to its focal point. The back focal length (BFL) is 48.8 mm, which is the distance from the lens's rear surface to its focal point.
The SLB-07-50PM 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, making it ideal for use in the 400-700 nm wavelength range. The lens has a thickness of 1.6 mm at the edge and 1.8 mm at the center, providing structural integrity and resistance to deformation.
