The SLSQ-50-120P is a Plano-Convex Lens with a diameter of 50.0 mm and a focal length of 120.0 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 3.0 mm at the edge and 9.0 mm at the center, with a radii of curvature of 55.2 mm for the convex surface. The back surface is planar, making this lens suitable for a wide range of optical applications. The effective focal length (EFL) is 120.0 mm, and the back focal length (BFL) is 113.8 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 to operate at a wavelength of 546.1 nm.
