This is a Plano-Convex lens from Thorlabs, designed with a spherical geometry and a circular base shape. The lens has a diameter of 1 inch (25.4 mm) and a thickness of 2 mm at the edge, which gradually increases to 2.8 mm at the center. The effective focal length (EFL) of this lens is 200 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. The inner and outer radii of the lens are 0, indicating a plano-convex design. The front and back surfaces of the lens are coated with a YAG V-Coat, specifically designed for 532/1064 nm wavelengths. This coating enhances the lens's performance by reducing reflection and increasing transmission.
