This is a high-quality aspheric lens from Edmund Optics, with the catalog number 67-269. It is designed for use in ultraviolet (UV) applications, with a wavelength of 587.6nm. The lens is made from HPFS7980 Corning, a type of fused silica known for its excellent optical properties and durability.
The lens has a diameter of 15mm and a numerical aperture (NA) of 0.6. The effective focal length (EFL) is 12.5mm, making it suitable for a wide range of optical systems. The lens features a UV coating on both the front and back surfaces, designed to enhance its performance in the UV range of 250-425nm.
The lens geometry is carefully designed to optimize its performance. It has an inner radius of 0mm and an outer radius of 0mm. The thickness at the edge is 2.47mm, while the thickness at the center is 9mm. The lens has an aspheric shape, with a first radius of curvature (R1) of 5.731mm and a second radius of curvature (R2) of 0mm. The back focal length (BFL) is 6.33mm.
The lens also features a sophisticated coating on both the front and back surfaces. The front surface is coated with EDM UV 250-425nm, a coating designed to enhance the lens's performance in UV applications. The back surface is also coated with the same coating for consistency and optimal performance.
