The SLSQ-50-170N is a Plano-Concave Lens with a diameter of 50.0 mm and a focal length of -170.0 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 spherical shape, with a center thickness of 3.0 mm and an edge thickness of 7.1 mm. The inner and outer radii are both 0.0 mm, indicating a uniform curvature. The radius of curvature (R1) is -78.2 mm, and the back focal length (BFL) is -172.1 mm. The effective focal length (EFL) is -170.0 mm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means that the lens can be used in a wider range of applications without worrying about potential coating incompatibilities.
