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

The SLSQK-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, and is manufactured from fused silica, a material known for its excellent optical properties and durability.

The lens geometry includes a thickness edge of 7.6 mm and a thickness center of 2 mm, providing a sleek and compact design. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The radius of curvature (R1) is -23 mm, and the back focal length (BFL) is -51.4 mm, further emphasizing the concave nature of the lens.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still suitable for various applications where a negatively powered lens is required. The wavelength of 546.1 nm suggests its use in visible light applications.
