84-341 50mm Dia. UVFS Aspheric Lens; EFL=50mm; NA=0.5 UV-VIS 250-700nm

The 84-341 50mm Dia. UVFS Aspheric Lens is a high-quality optical component sourced from Edmund Optics. This lens is designed with a base shape of a circle and is constructed from UV-VIS coated UV fused silica, ensuring durability and excellent optical performance. The lens has a diameter of 50mm and a thickness of 3.49mm at the edge, making it suitable for a wide range of applications.

The lens features an effective focal length (EFL) of 50mm, which is the distance from the lens's optical center to the point at which the light rays converge. This EFL makes the lens ideal for use in systems where a moderate focal length is required. The lens also has a numerical aperture (NA) of 0.5, which is a measure of the light-gathering ability of the lens. A higher NA allows for a greater light-gathering capability, making this lens suitable for applications where high light-gathering efficiency is required.

The lens is coated with the EDM UV-VIS std curve on both the front and back surfaces. This coating enhances the lens's transmission in the UV-VIS range (250-700nm), reducing reflection and improving overall system performance. The lens's geometry includes an inner radius of 0mm, an outer radius of 0mm, and a thickness at the center of 19.5mm. The aspheric design of the lens helps to reduce spherical aberration, improving the image quality and ensuring accurate focusing.
