69-320 6.0mm Dia. x 60.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
This is a 60mm diameter, 600mm focal length plano-convex lens, designed for use with a 405nm wavelength and featuring a laser V-coat on both surfaces. The lens is sourced from the reputable vendor, Edmund Optics.
The lens has a base shape of a circle, with a diameter of 6mm and a thickness at the edge of 1.45mm, gradually increasing to 1.6mm at the center. The effective focal length (EFL) is 60mm, and the first radius of curvature (R1) is 31.01mm. The back focal length (BFL) is 58.95mm, and the lens does not have any inner or outer radius.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The coating on both the front and back surfaces is the edm las v-coat 405, specifically designed for use with 405nm lasers. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
