The SLB-25-90PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 25.0 mm and a focal length of 90.0 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 46.71 mm, and the lens has an effective focal length (EFL) of 90 mm. The lens's thickness at the edge is 2 mm, while the center thickness is 3.7 mm. The back focal length (BFL) of the lens is 87.6 mm.
The SLB-25-90PM lens is coated with Opt M on both the front and back surfaces. This coating enhances the lens's performance in the spectral range of 400-700 nm, providing improved transmission and reduced reflection.
