The SLB-30-40PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 30.0 mm and a focal length of 40.0 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 20.76 mm. The lens has an effective focal length (EFL) of 40.0 mm and a back focal length (BFL) of 34.5 mm. The thickness at the edge of the lens is 2.0 mm, while the thickness at the center is 8.4 mm.
The SLB-30-40PM is coated with Opt M on both the front and back surfaces. This coating enhances the lens's performance in the spectral range of 400-700nm, providing improved transmission and reduced reflection.
