SLSQ-40-50N 40.0 mm Dia. x -50.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-40-50N is a Plano-Concave Lens, a type of spherical lens with a concave shape, sourced from OptoSigma. This lens is designed with a base shape that is circular and has a diameter of 40.0 mm. The lens's edge thickness measures at 13.6 mm, while its center thickness is significantly less at 2.0 mm.

The effective focal length (EFL) of this lens is -50.0 mm, indicating that it is a negative or diverging lens, which spreads out light rays. The first radius of curvature (R1) is -23.0 mm, and the back focal length (BFL) is -51.4 mm. The lens does not have an inner or outer radius, suggesting a uniform curvature.

This lens is made of fused silica, a high-purity glass with excellent optical transmission and a low coefficient of thermal expansion. The material ID for this lens is "fused sil mal-1965", indicating its specific type and properties.

The lens is designed to operate at a wavelength of 546.1 nm. It does not have any coating, which means it is uncoated. This could lead to a decrease in transmission and an increase in reflection, especially at larger angles of incidence. However, uncoated lenses are often more cost-effective and can be suitable for many applications.
