This is a LA1509-YAG N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Thorlabs. The lens, which has a diameter of 1 inch, is designed with a focal length of 100.0 mm, making it suitable for a wide range of optical applications.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material, also known as Schott glass, is known for its low auto-fluorescence, high damage threshold, and excellent transmission in the visible and near-infrared regions.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The radius of curvature of the curved surface is 51.5 mm, and the back focal length is 97.28 mm. The edge thickness of the lens is 2 mm, while the center thickness is 3.6 mm.
The LA1509-YAG lens is coated with a YAG V-Coat, specifically designed for 532/1064nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for laser applications.
The lens is currently in stock, and you can find more information about it on Thorlabs' official website.
