SLSQ-25.4B-200N 25.4 mm Dia. x -199.7 mm FL; Double-Concave Lens Uncoated

The SLSQ-25.4B-200N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use in a wide range of optical systems, boasts a diameter of 25.4 mm and a focal length of -199.7 mm, making it a versatile choice for various applications.

The lens is made from 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-concave geometry, with radii of curvature of -184 mm and 184 mm for the first and second surfaces, respectively. This geometry results in a back focal length of -200.4 mm.

The lens has a center thickness of 2 mm and an edge thickness of 2.9 mm, providing robustness and stability. Despite its robust construction, the lens is lightweight, making it easy to handle and integrate into optical systems.

The SLSQ-25.4B-200N is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means that the lens is less susceptible to damage from environmental factors or mishandling.

The lens is designed to work at a wavelength of 546.1 nm, making it suitable for use in systems operating in the visible light spectrum. It is in stock and ready for immediate use or integration into your optical system.
