The SLB-40-90PM is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of 90.0 mm. This lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens features a Plano-Convex geometry, with a center thickness of 6.5 mm and an edge thickness of 2 mm. This geometry, combined with the lens's diameter and focal length, results in an EFL (Effective Focal Length) of 90.0 mm and a BFL (Back Focal Length) of 85.7 mm.
The SLB-40-90PM is coated with an Opt M coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
