This is a 50mm diameter, 100mm 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, and is currently in stock.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a 1.58mm thickness at the edge, increasing to 9mm at the center. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 45.85mm. The back focal length (BFL) is 93.84mm, and both the inner and outer radii are 0mm.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent transmission properties in the ultraviolet (UV) region, making it ideal for use with the 405nm wavelength.
The lens features a laser V-coat coating on both the front and back surfaces. This coating is specifically designed to enhance the performance of the lens when used with lasers, providing improved damage threshold and laser-induced damage.
