32-708 18mm Dia. x 27mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts an 18mm diameter and a focal length of 27mm, making it suitable for a wide range of optical applications. 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 coating of MgF2 on both the front and back surfaces. This coating is standard across Edmund Optics' products and is designed to provide superior performance in the wavelength range of 400-700nm. The MgF2 coating reduces reflection and increases transmission, enhancing the overall efficiency of the optical system.
The geometry of the lens is meticulously designed, with an edge thickness of 2.42mm and a center thickness of 5.5mm. The lens's effective focal length (EFL) is 27mm, and the back focal length (BFL) is 25.25mm. The radii of curvature for the first and second surfaces are 27.08mm and -27.08mm, respectively. The lens's shape is spherical, ensuring high-quality imaging and minimal aberrations.
