SLSQ-30-250N 30.0 mm Dia. x -250.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-30-250N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens, with a diameter of 30.0 mm, is designed for use in systems with a wavelength of 546.1 nm. The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The lens features a concave shape with a radius of curvature of -115 mm, resulting in a back focal length of -251.4 mm. The edge thickness of the lens is 3 mm, while the center thickness is 2 mm. The effective focal length (EFL) of the lens is -250 mm, which is the distance from the lens's principal point to the focal point.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing protection against environmental factors. However, this lens is designed to be used in its bare form, leveraging the inherent properties of the fused silica material.
