This is a 50.0mm diameter by 100.0mm focal length Plano-Convex lens, designed for use with a 785nm wavelength and featuring a Laser V-Coat from Edmund Optics. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a 51.68mm radius of curvature (RoC) for the first surface and a back focal length of 93.41mm. The lens has an edge thickness of 3.55mm and a center thickness of 10mm. The effective focal length (EFL) of the lens is 100mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features a Laser V-Coat coating on both the front and back surfaces, specifically designed for use with a 785nm wavelength. This coating enhances the lens's performance by reducing reflections and increasing transmission.
