48-321 25.0mm Dia. x -50 FL; UV-AR Coated; UV Plano-Concave Lens 250-425nm
The 48-321 is a UV-AR coated, UV plano-concave lens with a diameter of 25.0mm and a focal length of -50.0mm. This lens is sourced from Edmund Optics, a leading provider of optical components. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it suitable for a range of UV-based applications.
The lens is constructed from fused silica, a material with a high transmittance across the UV spectrum. This ensures optimal performance and minimal signal loss when used within its designated wavelength range. The lens features a spherical shape, with a base shape of circular, and a planoconcave geometry. The center thickness of the lens is 2.0mm, while the edge thickness measures 5.52mm.
The lens is coated with a standard UV AR coating on both the front and back surfaces. This coating is designed to enhance the lens's performance within the UV spectrum, reducing unwanted reflections and increasing transmission. The coating also provides protection against environmental factors, ensuring the longevity and durability of the lens.
