46-313 9.0mm Dia. x -27 FL; UV-AR Coated; UV Plano-Concave Lens 250-425nm
The 46-313 is a 9.0mm diameter Plano-Concave Spherical Lens with a focal length of -27, sourced from Edmund Optics. This lens is designed for use within the ultraviolet (UV) spectrum, specifically between 250-425nm.
The lens is made from fused silica (mal-1965), a material known for its high transparency in the UV range. It features a standard UV Anti-Reflective (AR) coating on both the front and back surfaces, which enhances its performance in UV applications by reducing surface reflections and increasing transmission.
The lens has a thickness of 2.73mm at the edge and 2mm at the center, providing a robust structure while maintaining a low profile. The inner and outer radii are both 0, indicating a flat surface on both sides of the lens. The back focal length (BFL) is -28.42mm, and the effective focal length (EFL) is -27mm.
This lens is an excellent choice for applications that require UV transmission and a negative focal length, such as UV imaging systems, spectroscopy, and beam shaping. The 46-313 is currently in stock, as indicated by its valid weblink status.
