SLSQ-20-30P 20.0 mm Dia. x 30.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-30P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 30.0 mm, sourced from the reputable vendor OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The lens geometry is characterized by its base shape, which is circular, and its geometry, which includes a diameter of 20.0 mm, a thickness at the edge of 2.0 mm, and a thickness at the center of 6.3 mm. The effective focal length (EFL) is 30.0 mm, and the radius of curvature (R1) is 13.8 mm. The back focal length (BFL) is 25.7 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still suitable for a wide range of applications due to the high quality of the fused silica material. The wavelength for this lens is 546.1 nm.
