SLB-50.8-100N 50.8 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

The SLB-50.8-100N is a Plano-Concave Lens with a 50.8 mm diameter and a focal length of -100.0 mm, making it a negatively powered lens. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is uncoated. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens's geometry includes a thickness edge of 9.6 mm and a thickness center of 3 mm, providing a robust structure. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the concave surface is represented by a radius of -51.9 mm. The back focal length (BFL) is -102 mm, which is slightly longer than the focal length due to the lens's thickness.

This lens is designed for use in the visible light spectrum, specifically at a wavelength of 546.1 nm. It is suitable for various applications that require a negative lens, such as beam expansion, image reduction, or correcting optical systems. The uncoated version of this lens is ideal for applications where cost-effectiveness is a priority, or where specific coating requirements are not needed.

Please note that the lens is spherical, meaning it has the same curvature in all meridional sections, which is a common feature in many optical lenses. This lens type is also circular, making it suitable for use in circular optical systems.
