SLSQ-20B-20P 20.0 mm Dia. x 21.5 mm FL; Double-Convex Lens Uncoated
The SLSQ-20B-20P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 20.0 mm and a focal length of 21.5 mm, is designed for use in a wide range of optical applications.
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 18.4 mm for both the first and second surfaces. The center thickness of the lens is 7.9 mm, while the edge thickness is 2 mm.
The lens is uncoated, which means it does not have any anti-reflective coatings. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses can exhibit higher levels of reflection, which may affect the performance of the optical system.
The SLSQ-20B-20P is available from OptoSigma's website, and the link provided indicates that it is currently in stock. This makes it an ideal choice for users who need a reliable and readily available optical component for their systems.
