This is a Plano-Convex Lens, type 38-567, with a diameter of 35.0mm and a focal length of 100.0mm. The lens is sourced from the reputable vendor, Edmund Optics. It is designed for use within the Visible to Near-Infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400-1000nm.
The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability. The base shape of the lens is circular, and it features a spherical geometry. The edge thickness of the lens is 1.45mm, while the center thickness is 4.5mm. The effective focal length (EFL) is 100.0mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 97.03mm, and the inner and outer radii are both 0mm.
The lens is coated with a VIS-NIR coating, specifically 'edm visnir0sp2002000', on both the front and back surfaces. This coating enhances the lens's performance within the VIS-NIR spectrum, providing improved transmission and reduced reflection.
