This is a 12.0mm diameter x 24.0mm focal length Plano-Convex lens, designed for use with a 980nm wavelength and featuring a high-quality laser 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 12.0mm diameter, a 1.25mm thickness at the edge, and a 22.15mm thickness at the center. The effective focal length (EFL) is 24.0mm, and the radius of curvature (R1) is 12.42mm. The back focal length (BFL) is also 22.15mm, and both the inner and outer radii are 0.
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 specifically designed for 980nm lasers on both the front and back surfaces, ensuring optimal performance and durability.
