89-150 12mm Dia. x 12mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm

This is a 12mm diameter, 12mm focal length double-convex lens, sourced from the reputable optical components vendor, Edmund Optics. The lens is made from n-SF5 Schott material, a high-index glass often used in high-performance optical systems due to its excellent optical properties.

The lens features a double-convex geometry, characterized by two spherical surfaces that curve outwards, away from the optical axis. This design is particularly useful for imaging applications, as it provides a wide field of view and low distortion. The lens has an effective focal length (EFL) of 12mm, which is the distance from the lens's principal point to the image plane when the lens is focused at infinity.

The lens is coated with EDM VIS-EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350-700nm. This coating reduces surface reflections, improving light transmission and enhancing the overall performance of the lens.

The lens has a center thickness of 3.85mm and an edge thickness of 1.41mm, providing robustness and structural integrity. The inner and outer radii are not specified, indicating that they are not critical to the lens's performance or design.
