This is a 12.0mm diameter x 100.0mm focal length Plano-Convex lens, specifically 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 a Spherical Lens of the Sub Type Plano-Convex, with a base shape of Circular. The geometry of the lens includes a diameter of 12.0mm, a thickness at the edge of 2.15mm, and a thickness at the center of 2.5mm. The effective focal length (EFL) is 100.0mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 98.35mm, and both the inner and outer radii are 0mm.
The lens is made from n-BK7 Schott, a high-quality optical glass. The coating on the lens is the edm las v-coat 405, which is specifically designed for use with a 405nm wavelength. This coating is applied to both the front and back surfaces of the lens.
