SLSQ-20B-80P 20.0 mm Dia. x 80.6 mm FL; Double-Convex Lens Uncoated
The SLSQ-20B-80P 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 80.6 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 a center thickness of 3.4 mm and an edge thickness of 2 mm. The radii of curvature for the first and second surfaces are 73.6 mm and -73.6 mm, respectively, resulting in a back focal length of 79.4 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.
The SLSQ-20B-80P is currently in stock and available for immediate purchase. For more information, including pricing and shipping details, please refer to the vendor's website.
