48-310 25mm Dia. x 150mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
This 48-310 UV-AR coated, UV double-convex lens, sourced from Edmund Optics, boasts a 25mm diameter and a 150mm focal length. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it an ideal choice for applications requiring ultraviolet light transmission.
The lens features a standard UV-AR coating on both the front and back surfaces, which is part of Edmund Optics' standard curve coating. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and minimizing lens flare.
The lens's geometry is characterized by a 2.54mm edge thickness and a 3.68mm center thickness. It has a 136.96mm radius of curvature for the first surface and a -136.96mm radius for the second surface, resulting in a back focal length of 148.37mm. The lens is spherical in shape, and while the inner and outer radii are listed as 0, this likely refers to the fact that these dimensions are not relevant to the lens's design or use.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent transmission properties across a wide range of wavelengths, including the UV spectrum, and its high resistance to thermal shock and chemical etching.
