The SLB-50-90PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 50.0 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 lens is defined by a radius of 46.71 mm on the curved side. The lens has an effective focal length (EFL) of 90.0 mm and a back focal length (BFL) of 83.2 mm. The edge thickness of the lens is 3.0 mm, while the center thickness is 10.3 mm.
The SLB-50-90PM is coated with an Opt M coating 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. The lens is currently in stock and available for immediate purchase.
