SLB-80B-1000P 80.0 mm Dia. x 1000.7 mm FL; Double-Convex Lens Uncoated

The SLB-80B-1000P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 80.0 mm, is designed for use in a wide range of optical applications, thanks to its precise geometry and high-quality materials.

The lens features a base shape of a circle, with a thickness of 3.0 mm at the edge and 4.5 mm at the center. The effective focal length (EFL) of this lens is 1000.7 mm, making it suitable for applications that require a long focal length. The first radius of curvature (R1) is 1038 mm, while the second radius of curvature (R2) is -1038 mm, indicating the double-convex nature of the lens. The back focal length (BFL) of this lens is 999.3 mm.

The SLB-80B-1000P is made from n-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. This lens is uncoated, which means it does not have any additional layers to enhance its optical performance. However, the uncoated version can still provide good performance for many applications, especially where high transmission and low reflection are not critical.

This lens is designed to work with a wavelength of 546.1 nm, which is within the visible light spectrum. It is a spherical lens, which is the most common type of lens due to its ease of manufacturing and versatility.
