This 34-136 12mm Dia. x 36mm FL Fused Silica Plano-Convex Lens, available from Edmund Optics, is a high-quality optical component designed for use in laser applications at a wavelength of 1064nm. The lens is spherical in shape, with a base shape of circular, and features a plano-convex geometry.
The lens has a diameter of 12mm and a thickness at the edge of 1.37mm, while the thickness at the center is 2.5mm. The effective focal length (EFL) of the lens is 36mm, and the radius of curvature (R1) is 16.51mm. The back focal length (BFL) is 34.29mm, and both the inner and outer radii are 0mm.
The lens is made from fused silica, a material with the material ID 'fused sil mal-1965'. This material is known for its excellent optical properties, including high transparency and resistance to thermal shock.
The lens features a laser V-coat coating on both the front and back, specifically designed for use at 1064nm. This coating enhances the lens's performance in laser applications, improving transmission and reducing reflection.
