SLSQK-50-100N 50.0 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

OptoSigma's SLSQK-50-100N is a fused silica plano-concave lens, uncoated and designed for general use. This lens, with a diameter of 50.0 mm, is ideal for applications that require a large aperture. The lens's concave shape, defined by a radius of curvature (R1) of -46 mm, results in a back focal length (BFL) of -102.1 mm and an effective focal length (EFL) of -100 mm.

The lens's edge thickness is 10.4 mm, while the center thickness is 3 mm, providing sufficient structural integrity. Despite its robust design, the lens remains lightweight, making it suitable for various applications. The lens's material, fused silica, ensures high transmittance in the ultraviolet, visible, and near-infrared regions of the spectrum, making it a versatile choice for many optical systems.

Please note that this lens is uncoated, which may affect its performance in specific applications. Uncoated lenses can suffer from reduced transmission due to surface reflections, and they may also be more susceptible to environmental contaminants. However, uncoated lenses are often more cost-effective and can be a good choice for applications where these factors are not critical.
