SLB-50.8B-150P 50.8 mm Dia. x 151.2 mm FL; Double-Convex Lens Uncoated

The SLB-50.8B-150P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 50.8 mm and a focal length of 151.2 mm, is designed for use in a wide range of optical applications.

The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry. The radius of curvature for the first surface is 155.7 mm, while for the second surface it is -155.7 mm. The lens has a thickness of 2.8 mm at the edge and 7 mm at the center. The effective focal length (EFL) is 151.2 mm, and the back focal length (BFL) is 148.9 mm.

The lens is uncoated, which means it does not have any anti-reflective coatings. This may result in higher reflective losses, but it also means that the lens is more cost-effective and suitable for applications where such coatings are not required.

The lens is currently in stock and can be purchased directly from the OptoSigma website. It is a versatile component that can be used in various optical systems, making it a valuable addition to any optics laboratory or optical design project.
