48-290 25mm Dia. x 200mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 48-290 is a UV Plano-Convex Lens, UV-AR coated, with a 25mm diameter and a focal length of 200mm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical elements. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it ideal for applications such as UV imaging, spectroscopy, and other UV-based research or industrial processes.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a thickness of 2.02mm at the edge and 2.88mm at the center. The effective focal length (EFL) is 200mm, and the back focal length (BFL) is 198.02mm. The lens is made from fused silica, a material with the material ID of mal-1965, which is known for its excellent optical properties and durability.
The lens features UV-AR coatings on both the front and back surfaces. These coatings are standard curve EDUM UV coatings, designed to enhance the lens' performance within the UV spectrum by reducing surface reflections and increasing transmission. The coating specifications are not provided in the data, but users can refer to the vendor's website for more detailed information.
