SLSQ-50.8-80N 50.8 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated

OptoSigma's SLSQ-50.8-80N is a fused silica plano-concave lens, uncoated and designed for general use. This lens boasts a diameter of 50.8 mm and a focal length of -80.0 mm, making it suitable for a wide range of applications.

The lens is made of fused silica, a material known for its excellent thermal stability, chemical resistance, and transmission properties. The material's low coefficient of thermal expansion minimizes the risk of thermal shock and ensures dimensional stability over a wide temperature range. Additionally, fused silica's high chemical resistance makes it suitable for use in harsh environments.

The SLSQ-50.8-80N features a plano-concave geometry, with a center thickness of 3 mm and an edge thickness of 13.2 mm. This geometry, combined with its focal length, makes the lens ideal for use in imaging systems, beam shaping, and other applications where a negative lens is required.

The lens is uncoated, which means it does not have any anti-reflective or other surface treatments. While this may result in higher reflective losses compared to coated lenses, it also means that the lens is more robust and less prone to damage.
