SLB-40B-150P 40.0 mm Dia. x 150.8 mm FL; Double-Convex Lens Uncoated
The SLB-40B-150P is a high-quality, double-convex lens offered by OptoSigma. This lens, with a diameter of 40.0 mm and a focal length of 150.8 mm, is designed for use in a wide range of optical applications.
The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and high Abbe number. The double-convex geometry, with radii of curvature of 155.7 mm and -155.7 mm, provides a high degree of focusing power. The lens has an edge thickness of 2 mm and a center thickness of 4.6 mm, ensuring robustness and durability.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens is less susceptible to damage and contamination. The effective focal length (EFL) of the lens is 150.8 mm, and the back focal length (BFL) is 149.2 mm.
This lens is a great choice for applications that require a high-quality, double-convex lens with a long focal length. It is available for purchase from the OptoSigma website, and the link provided indicates that it is currently in stock.
