88-979 20.0mm Dia. x 150.0mm FL; Plano-Convex Lens Laser V-Coat 405nm

This is a 20.0mm diameter, 150.0mm focal length Plano-Convex lens, designed for use with a 405nm wavelength and featuring a laser V-coat on both the front and back surfaces. The lens is sourced from the reputable vendor, Edmund Optics.

The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes an edge thickness of 2.35mm and a center thickness of 3mm. The effective focal length (EFL) is 150.0mm, and the radius of curvature (R1) is 77.52mm. The back focal length (BFL) is 148.02mm, and both the inner and outer radii are 0mm.

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 coating on both the front and back surfaces, specifically designed for 405nm lasers. This coating enhances the lens's performance by reducing surface reflections and improving transmission.
