SLSQ-25B-50P 25.0 mm Dia. x 51.0 mm FL; Double-Convex Lens Uncoated
The SLSQ-25B-50P is a high-quality, double-convex lens offered by OptoSigma. This lens, with a diameter of 25.0 mm and a focal length of 51.0 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 double-convex geometry, with radii of curvature of 46 mm for the first surface and -46 mm for the second surface. This geometry results in a back focal length of 49.0 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 is less susceptible to damage and contamination. The edge thickness of the lens is 2.0 mm, and the center thickness is 5.5 mm.
The SLSQ-25B-50P is available from OptoSigma and is currently in stock. It is a versatile lens that can be used in various applications, making it a valuable addition to any optical setup.
