This is a Plano-Convex lens, type SLB-40-1000PM, sourced from OptoSigma. The lens has a diameter of 40.0 mm and a focal length of 1000.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott material, a popular choice due to its excellent optical properties and versatility.
The lens's geometry is characterized by a thickness of 2.0 mm at the edge and 2.4 mm at the center. The front and back surfaces of the lens are coated with opt m, a coating that enhances the lens's performance in the wavelength range of 400-700nm. This coating is designed to reduce reflection and increase transmission, thereby improving the overall efficiency and quality of the optical system.
The lens's shape is spherical, with a radius of curvature (r1) of 519 on the convex side. The back surface of the lens is planar, and the lens has an effective focal length (EFL) of 1000.0 mm. The lens's inner and outer radii are both 0, indicating a uniform curvature across the lens surface.
