SLSQ-20-40P 20.0 mm Dia. x 40.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-40P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 40.0 mm, making it ideal for a wide range of optical applications. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is available in fused silica material, specifically identified as 'fused sil mal-1965'.

The lens geometry is characterized by its spherical shape, with a center thickness of 5.0 mm and an edge thickness of 2.0 mm. The inner and outer radii are 0 mm each, indicating a uniform curvature across the lens surface. The effective focal length (EFL) is 40.0 mm, and the back focal length (BFL) is 36.6 mm. The radius of curvature (R1) is 18.4 mm.

Notably, this lens is uncoated, which means 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, users should be aware that uncoated lenses can exhibit higher levels of reflection, which may affect overall system performance.

The lens is currently in stock and can be purchased directly from the vendor's website, with the provided weblink offering a direct path to the product page.
