This is a laser grade plano-convex lens, designed and manufactured by Edmund Optics, a renowned vendor in the optical industry. The lens boasts a diameter of 25.4mm and a focal length of 100mm, making it suitable for a wide range of applications that require precise focusing of light.
The lens is made from UVFS, a material with a refractive index of 1.965, which is often used in ultraviolet (UV) applications due to its excellent transmission properties in this region of the spectrum. The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light collection and focusing.
The lens is coated with Edmund Optics' Laser V-Coat 355, a proprietary coating that is specifically designed for use with 355nm lasers. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the efficiency of the system in which it is used.
The lens has a center thickness of 4mm and an edge thickness of 2.13mm, providing a robust and durable structure. The inner and outer radii are 0mm, indicating a sharp transition between the flat and curved surfaces. The lens's effective focal length (EFL) is 100mm, and the back focal length (BFL) is 97.32mm.
