63-584 20mm Dia. x 50mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 20mm diameter, double-convex lens with a focal length of 50mm, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a standard MgF2 coating on both the front and back surfaces, which is designed to enhance the lens' performance in the wavelength range of 400-700nm. This coating reduces reflection and increases transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The lens geometry includes an edge thickness of 1.52mm and a center thickness of 3.5mm. The front and back radii of curvature are 51.08mm and -51.08mm respectively, resulting in a back focal length of 48.84mm. The lens is designed to operate at a wavelength of 587.6nm.
