The SLSQ-15B-90P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 15.0 mm, is designed for use in various optical systems that require a focal length of 90.5 mm.
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 82.8 mm for both surfaces. The center thickness of the lens is 2.7 mm, while the edge thickness is 2 mm.
The lens is uncoated, which means it does not have any anti-reflective coatings. This may result in some reflection of light at the lens surfaces, but it also means the lens is less susceptible to damage from environmental factors.
