SLB-40B-70P 40.0 mm Dia. x 71.3 mm FL; Double-Convex Lens Uncoated
The SLB-40B-70P is a high-quality double-convex lens, sourced from the reputable optical component manufacturer, OptoSigma. This lens, with a diameter of 40.0 mm and a focal length of 71.3 mm, is designed for use in a wide range of optical applications.
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 a center thickness of 7.6 mm and an edge thickness of 2 mm. The effective focal length (EFL) of the lens is 71.3 mm, and the back focal length (BFL) is 68.7 mm.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance loss, 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-70P is currently in stock and available for immediate purchase. For more information, including technical specifications and pricing, please refer to the vendor's website.
