This is a 25.0mm diameter, 175.0mm focal length Plano-Convex lens, specifically designed for use with a 633nm laser and featuring a V-Coat. The lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a thickness edge of 2.63, a thickness center of 3.5, and an effective focal length (EFL) of 175.0mm. The first radius of curvature (R1) is 90.47, and the back focal length (BFL) is 172.85. The lens does not have an inner or outer radius.
The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The lens features a V-Coat on both the front and back, specifically an edm las v-coat 633. This coating is designed for use with 633nm lasers, providing excellent laser damage threshold and high transmission.
