SLB-15B-40P 15.0 mm Dia. x 40.6 mm FL; Double-Convex Lens Uncoated
The SLB-15B-40P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 15.0 mm and a focal length of 40.6 mm, is designed for use in a wide range of optical applications.
The lens is made from n-bk7 schott, a popular material 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 3.4 mm and an edge thickness of 2 mm. The effective focal length (EFL) of the lens is 40.6 mm, and the back focal length (BFL) is 39.4 mm.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher level of reflection, 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 lens is currently in stock and can be purchased directly from the OptoSigma website. It is part of a larger range of uncoated lenses offered by the vendor, providing users with a wide variety of options to choose from based on their specific needs and applications.
