SLB-20-120PM 20.0 mm Dia. x 120.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-20-120PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 20.0 mm and a focal length of 120.0 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 62.28 mm, and the lens has an effective focal length (EFL) of 120.0 mm. The thickness of the lens at the edge is 2.0 mm, while the center thickness is 2.8 mm. The back focal length (BFL) of the lens is 118.2 mm.
The SLB-20-120PM 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, making it ideal for use in applications such as fluorescence microscopy, spectroscopy, and beam shaping.
According to the vendor's website, the lens is currently in stock, ensuring quick delivery for your optical project needs.
