SLSQ-25B-170P 25.0 mm Dia. x 170.5 mm FL; Double-Convex Lens Uncoated

The SLSQ-25B-170P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 25.0 mm and a focal length of 170.5 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 156.4 mm and -156.4 mm for the first and second surfaces, respectively. This geometry results in a back focal length of 169.5 mm.

The lens has a thickness of 2 mm at the edge and 3 mm at the center, providing robustness and stability. The design wavelength for this lens is 546.1 nm. It's important to note that the lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This may affect its performance in certain applications, particularly those requiring high transmission or low reflectance.

According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. The website also provides further technical details and specifications, as well as options for customization.
