67-220 50mm Dia. x 150mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 67-220 is a UV-AR coated plano-convex lens, boasting a 50mm diameter and a focal length of 150mm. This lens, sourced from Edmund Optics, is designed for use within the ultraviolet spectrum, specifically between 250 and 425nm. The lens is made from fused silica, a material known for its high transparency and durability.
The plano-convex design of this lens, where one side is flat and the other is curved, provides a number of benefits. It allows for a greater degree of light bending compared to a bi-convex lens of the same diameter, making it ideal for applications where a compact, high-performance lens is required. The lens also features an anti-reflective coating on both the front and back surfaces, further enhancing its performance by reducing unwanted reflections and increasing transmission.
The geometry of the lens is carefully controlled, with a thickness at the edge of 2.29mm and a center thickness of 7mm. The lens's inner and outer radii are 0mm, and its effective focal length (EFL) is 150mm. The radius of curvature (R1) is 68.77mm, and the back focal length (BFL) is 145.2mm.
