SLSQ-25B-70P 25.0 mm Dia. x 70.8 mm FL; Double-Convex Lens Uncoated

The SLSQ-25B-70P is a high-quality double-convex lens, sourced from the reputable optical vendor, OptoSigma. This lens, with a diameter of 25.0 mm and a focal length of 70.8 mm, is designed for use in a wide range of optical 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-convex geometry, with radii of curvature of 64.4 mm for the first surface and -64.4 mm for the second surface. This geometry results in a back focal length of 69.2 mm.

The lens has a central thickness of 4.5 mm and an edge thickness of 2 mm, providing robustness and durability. Despite its robust construction, the lens is lightweight and easy to handle, making it ideal for use in portable or handheld devices.

The SLSQ-25B-70P is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may be suitable for applications where such coatings are not required or desirable. However, for applications where minimizing surface reflections is important, additional coatings may be necessary.
