This is a Plano-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens, identified as the 38-512, is a Spherical Lens with a base shape of Circular, and a diameter of 12.5mm. It boasts a thickness of 1.22mm at the edge, while the center thickness is slightly more at 1.6mm. The Effective Focal Length (EFL) of this lens is 100mm.
The lens's front and back surfaces are coated with the EDM VISNIR0SP2002000 coating, a VIS-NIR anti-reflection coating designed for use in the 400-1000nm wavelength range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm. The first radius of curvature (R1) is 51.68mm, and the back focal length (BFL) is 98.95mm. The material of the lens is n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
