This product is a Plano-Convex lens, sourced from the reputable optical vendor, Edmund Optics. The lens boasts a diameter of 40.0mm and a focal length of 400.0mm, making it a versatile choice for various 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 VIS-EXT coating on both the front and back surfaces. This coating is specifically designed to extend the visible range of the lens, making it suitable for use in wavelengths between 350-700nm. The coating also helps to reduce surface reflections, thereby improving the overall transmission of light through the lens.
The geometry of the lens is also noteworthy. It has an edge thickness of 4.03mm and a center thickness of 5mm. The radius of curvature of the convex surface is 206.72mm, and the back focal length is 396.7mm. The lens does not have an inner or outer radius, indicating a uniform thickness across the lens.
