LA1085-C N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=30.0 mm ARC 1050-1700nm

The LA1085-C is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7, a popular glass type known for its excellent optical properties, and is sourced from the reputable Schott glass manufacturer.

The lens has a diameter of 18.0 mm and a thickness of 1.8 mm at the edge, increasing to 4.7 mm at the center. It boasts an effective focal length (EFL) of 30.0 mm, making it suitable for applications that require a longer focal length. The lens's curvature is defined by a radius of 15.5 mm on the convex side, and its back focal length (BFL) is 26.8 mm.

The LA1085-C is coated with Thorlabs' proprietary broadband anti-reflection coating, which is designed to operate between 1050 and 1700 nm. This coating reduces surface reflections, thereby improving transmission and minimizing signal loss.

This lens is a spherical lens, meaning it has a spherical surface. The base shape is circular, which is a common shape for optical elements. The lens is available for purchase directly from Thorlabs, and as of the time of data collection, it is in stock.
