SLB-50.8-300N 50.8 mm Dia. x -300.0 mm FL; Plano-Concave Lens Uncoated

The SLB-50.8-300N is a Plano-Concave Lens with a diameter of 50.8 mm and a focal length of -300.0 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 popular optical glass due to its excellent optical properties and high homogeneity.

The lens's geometry includes a thickness edge of 5.1 mm and a thickness center of 3 mm, providing a sleek and compact design. The inner and outer radii are both 0 mm, indicating a flat surface on both sides of the lens. The back focal length (BFL) is -302 mm, slightly longer than the effective focal length (EFL) of -300 mm, which is typical for Plano-Concave lenses.

This lens is suitable for various applications, including beam expanding, image reduction, and light collimation. However, due to its uncoated nature, it may exhibit higher reflectivity and lower transmission compared to coated lenses. Therefore, it's essential to consider the environmental conditions and the specific application requirements when selecting this lens.
