This is a 65-470 6.0mm Dia. x 12.0mm FL Plano-Convex Lens, specifically designed for use with a 532nm wavelength and featuring a high-quality laser V-coat on both the front and back surfaces. The lens is sourced from the reputable vendor, Edmund Optics.
The lens is a spherical design, with a base shape of a circle. It has a diameter of 6mm and a thickness at the edge of 0.83mm, while the center thickness is 1.6mm. The effective focal length (EFL) of the lens is 12mm, and the radius of curvature (R1) is 6.2mm. The back focal length (BFL) is 10.94mm, and both the inner and outer radii are 0mm.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens is coated with Edmund Optics' proprietary laser V-coat, designed specifically for 532nm. This coating provides high damage threshold, low scatter, and excellent laser-induced damage threshold (LIDT) performance.
