This is a laser grade plano-convex lens, 12mm in diameter and 36mm in focal length, specifically designed for use with a 355nm wavelength. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made of fused silica, a high-quality material with the material ID 1965, ensuring durability and reliability. It features a plano-convex geometry, meaning one side is flat while the other is curved, with a radius of curvature of 16.51mm. The lens has an inner radius of 0mm and an outer radius of 0mm.
The lens's thickness at the edge is 1.37mm, while the center thickness is 2.5mm. The effective focal length (EFL) is 36mm, and the back focal length (BFL) is 34.29mm.
The lens is coated with Edmund Optics' Laser V-Coat 355, a specialized coating designed for use with 355nm lasers. This coating is applied to both the front and back surfaces of the lens.
