This is a 50.0mm diameter, 175.0mm focal length plano-convex lens, offered by the renowned optical vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a VIS-EXT coating on both the front and back surfaces, which extends its usable wavelength range from 350 to 700nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it suitable for a wide range of applications, including imaging and laser systems.
The lens's geometry includes a 5.48mm edge thickness and a 9mm center thickness, providing robustness and ensuring minimal distortion. The inner and outer radii are 0mm, indicating a flat surface on one side and a curved surface on the other. The lens's effective focal length (EFL) is 175.0mm, and the back focal length (BFL) is 169.05mm.
The lens's shape is spherical, which is a common and versatile lens shape, suitable for a wide range of applications. The lens's base shape is circular, making it compatible with various optical systems and setups.
