The SLSQ-40B-100P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 40.0 mm and a focal length of 101.1 mm, is designed for use in a variety of optical systems.
The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The base shape of the lens is circular, and it features a spherical geometry with radii of curvature of 92 mm for the first surface and -92 mm for the second surface. This geometry results in a back focal length of 98.9 mm.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens can be used over a broad spectrum of wavelengths, making it a versatile choice for many applications.
