63-586 20mm Dia. x 80mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 20mm diameter, double-convex lens with a focal length of 80mm, 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, increases transmission, and improves the overall quality of the optical system in which the lens is used.
The geometry of the lens includes an edge thickness of 2.78mm and a center thickness of 4mm. The back focal length (BFL) is 78.67mm, and the effective focal length (EFL) is 80mm. The radii of the curvature for the first and second surfaces are 82mm and -82mm, respectively. The lens is spherical in shape, ensuring high-quality imaging and minimal aberration.
The lens is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
