This 34-150 50mm Dia. x 200mm 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 50mm and a thickness at the edge of 3.53mm, while the center thickness measures 7mm. The effective focal length (EFL) is 200mm, and the radius of curvature (R1) is 91.69mm. The back focal length (BFL) is 195.19mm, 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 is coated with a laser V-coat, specifically designed for use at 1064nm. This coating, applied to both the front and back surfaces of the lens, enhances its performance in laser applications by reducing reflections and increasing transmission.
