63-565 5mm Dia. x 20mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 5mm diameter, double-convex lens with a focal length of 20mm, 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 geometry of the lens includes an edge thickness of 1.19mm and a center thickness of 1.5mm. The front and back radii of curvature are 20.41mm and -20.41mm respectively, resulting in a back focal length of 19.5mm. The lens is spherical in shape, ensuring excellent image quality and minimal aberrations.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its high-quality materials, advanced coating, and precise geometry, this lens is an excellent choice for a wide range of optical applications.
