LA1540-C N-BK7 Plano-Convex Lens; Dia:0.5 in; f=15.0 mm ARC 1050-1700nm

The LA1540-C is a Plano-Convex lens, a type of spherical lens, manufactured by Thorlabs. This lens is designed with a circular base shape and features a diameter of 12.7 mm and a thickness of 1.8 mm at the edge, transitioning to 5.1 mm at the center. The effective focal length (EFL) of this lens is 15 mm, making it suitable for a variety of optical applications.

The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The curvature of the lens is defined by a radius of 7.7 mm on the convex side. The back focal length (BFL) is 11.6 mm, and the lens does not have any inner or outer radii.

The LA1540-C is coated with a broadband anti-reflection coating (ARC) that is designed to operate between 1050 nm and 1700 nm, making it ideal for use in near-infrared (NIR) applications. This coating helps to minimize surface reflections, thereby improving transmission and reducing signal loss.

According to the vendor's website, the LA1540-C is currently in stock, indicating its availability for immediate purchase and use. This lens, like all products from Thorlabs, is expected to meet high standards of quality and performance.
