This is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens, identified as the 63-568 model, boasts a 10mm diameter and a 15mm focal length, making it suitable for a wide range of optical applications.
The lens is made from the high-grade material, n-BK7 Schott, which is known for its excellent optical properties and durability. The front and back surfaces of the lens are coated with EDM MgF2 std curve, a coating that enhances the lens's performance by reducing surface reflections and increasing transmission in the 400-700nm wavelength range.
The lens's geometry is meticulously designed, with an edge thickness of 1.77mm and a center thickness of 3.5mm. The radii of curvature for the first and second surfaces are 14.88mm and -14.88mm, respectively, resulting in a back focal length of 13.8mm. The effective focal length of the lens is 15mm, making it a versatile tool for various optical systems.
