SLB-80B-500P 80.0 mm Dia. x 501.0 mm FL; Double-Convex Lens Uncoated

The SLB-80B-500P is a high-quality double-convex lens, boasting a diameter of 80.0 mm and a focal length of 501.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical elements.

The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry, with radii of curvature of 519 mm for the first surface and -519 mm for the second surface. This spherical shape ensures a high-quality, focused image.

The lens has a thickness of 3 mm at the edge and 6.1 mm at the center, providing structural integrity and resistance to deformation. The effective focal length (EFL) is 501 mm, and the back focal length (BFL) is 499 mm, indicating a long focal length that can capture detailed images from a distance.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections and increasing transmission, an uncoated lens can be advantageous in certain applications where a natural chromatic aberration is desired.
