SLB-40B-170P 40.0 mm Dia. x 170.7 mm FL; Double-Convex Lens Uncoated
The SLB-40B-170P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 40.0 mm and a focal length of 170.7 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 with a center thickness of 4.3 mm and an edge thickness of 2 mm. The effective focal length (EFL) of the lens is 170.7 mm, and the back focal length (BFL) is 169.3 mm.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectivity at the air-glass interfaces, it also means that the lens is more cost-effective and versatile, as it can be used in a wider range of wavelengths without the risk of coating damage.
The SLB-40B-170P is currently in stock and can be purchased directly from the OptoSigma website. With its robust design and high-quality materials, this lens is an excellent choice for anyone in need of a reliable and affordable double-convex lens.
