SLSQ-25.4B-100N 25.4 mm Dia. x -99.7 mm FL; Double-Concave Lens Uncoated
OptoSigma's SLSQ-25.4B-100N is a fused silica biconcave lens, uncoated, with a diameter of 25.4 mm and a focal length of -99.7 mm. This lens is designed for use in applications that require a high level of precision and clarity.
The lens is made from fused silica, a material known for its excellent optical properties, including a low coefficient of thermal expansion, high transmittance across a wide range of wavelengths, and high resistance to chemical and mechanical damage. The material is identified as "fused sil mal-1965" in the item data.
The SLSQ-25.4B-100N features a double-concave geometry, with a center thickness of 2 mm and an edge thickness of 3.8 mm. The radii of curvature for the two surfaces are -92 mm and 92 mm, respectively, resulting in a back focal length of -100.4 mm. The lens has no coating, which means it is uncoated and will have a higher reflectivity than coated lenses.
This lens is suitable for use in a variety of applications, including imaging systems, beam shaping, and laser applications. It is currently in stock and available for purchase through the vendor's website. The item data also includes a valid web link for easy access to more information about the lens.
