SLSQ-50.8-80P 50.8 mm Dia. x 80.0 mm FL; Plano-Convex Lens Uncoated
The SLSQ-50.8-80P is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 80.0 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 2.6 mm at the edge and 12.8 mm at the center, with a radius of curvature of 36.8 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 80.0 mm, and the back focal length (BFL) is 71.2 mm.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other coatings. While this may result in higher reflective losses, it also means that the lens can be used in a wider range of wavelengths without the risk of coating damage. The lens is designed for use at a wavelength of 546.1 nm.
