LA1540-YAG N-BK7 Plano-Convex Lens; Dia:0.5 in; f=15.0 mm YAG V-Coat 532/1064nm

This is a LA1540-YAG N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Thorlabs. The lens, with a diameter of 0.5 inches (12.7 mm), is designed for use in systems operating at 587.6 nm. It features a focal length of 15.0 mm, making it suitable for a wide range of optical applications.

The lens is made of N-BK7, a popular glass type known for its excellent optical properties. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light transmission and focusing. The lens has a center thickness of 5.1 mm and an edge thickness of 1.8 mm, providing robustness and durability.

The LA1540-YAG lens is coated with a YAG V-Coat, specifically designed for 532/1064 nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.

The item data also provides information about the lens's geometry, including the inner and outer radii, which are both 0 in this case. The back focal length (BFL) is 11.56 mm, and the effective focal length (EFL) is 15 mm.
