SLB-25-250PM 25.0 mm Dia. x 250.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-25-250PM 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 250.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass, and features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex).
The lens has a thickness of 2.0 mm at the edge and 2.6 mm at the center. The effective focal length (EFL) is 250.0 mm, and the radius of curvature (R1) is 129.75 mm. The back focal length (BFL) is 248.3 mm, and both the inner and outer radii are 0 mm.
The SLB-25-250PM is coated with Opt M on both the front and back, enhancing its performance in the 400-700nm wavelength range. This coating reduces reflection and increases transmission, making the lens ideal for use in laser applications and other settings where high transmission is required.
