SLSQK-50-80N 50.0 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated

The SLSQK-50-80N is a Plano-Concave Lens, sourced from OptoSigma, a renowned vendor in the optical industry. This lens is designed with a spherical shape, featuring a base shape of a circle, and is uncoated. The lens is fabricated from fused silica, a material with the material ID 'fused sil mal-1965'.

The lens has a diameter of 50.0 mm and a thickness at the edge of 12.8 mm. The center thickness of the lens is 3.0 mm. The effective focal length (EFL) of the lens is -80.0 mm, indicating its concave nature. The radius of curvature (R1) is -36.8 mm, and the back focal length (BFL) is -82.1 mm. The lens does not have any inner or outer radius specified, indicating it is a simple plano-concave lens.

The lens is designed to operate at a single wavelength of 546.1 nm. This wavelength is typically used in monochromatic applications. The lens is not coated, which means it does not have any anti-reflective or other surface treatments. This can be beneficial in certain applications where such coatings may interfere with the desired optical performance.
