SLSQ-50.8-90P 50.8 mm Dia. x 90.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-50.8-90P is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 90.0 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 a thickness of 2.7 mm at the edge and 11.4 mm at the center, with a radius of curvature of 41.4 mm for the convex surface. The back surface is planar, making it suitable for a wide range of optical applications. The effective focal length (EFL) is 90.0 mm, and the back focal length (BFL) is 82.2 mm.

Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means that the lens can be used over a broad spectral range, from ultraviolet to infrared, without concerns about coating performance.
