48-044 12mm Dia. x 45mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm

This is a 12mm diameter, UV-AR coated, UV Double-Convex Lens, with a focal length of 45mm, sourced from the renowned optical components vendor, Edmund Optics. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it ideal for applications such as UV imaging, spectroscopy, and other UV-based optical systems.

The lens features a double-convex geometry, characterized by two spherical surfaces that curve outwards, which is advantageous in focusing light onto a single point. The base shape is circular, and the lens has a center thickness of 2.99mm and an edge thickness of 2.1mm, providing robustness and durability.

The lens is made from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency in the UV range, making it suitable for UV applications. The lens's front and back surfaces are coated with the EDM UV STD CURVE coating, which is designed to enhance its performance in the UV spectrum by reducing surface reflections and increasing transmission.

The lens's effective focal length (EFL) is 45mm, and its back focal length (BFL) is 43.96mm, which are crucial specifications for designing and integrating the lens into optical systems. The inner and outer radii are 0, indicating that the lens is a simple double-convex lens without any additional features such as threads or mounts.
