SLSQ-30-50N 30.0 mm Dia. x -50.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-30-50N is a Plano-Concave Lens with a diameter of 30.0 mm and a focal length of -50.0 mm, making it a negatively powered lens. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. 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 geometry includes an edge thickness of 7.6 mm and a center thickness of 2 mm, providing a robust structure. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The back focal length (BFL) is -51.4 mm, slightly longer than the effective focal length (EFL) due to the thickness of the lens.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and a higher susceptibility to environmental factors, it also means the lens has a broader spectral range.

The SLSQ-30-50N is ideal for applications that require a negative lens with a specific focal length and diameter. Its high-quality fused silica material and robust structure make it suitable for use in various fields, such as metrology, beam shaping, and imaging systems.
