This is a high-quality double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 63-566 model, boasts a 5mm diameter and a focal length of 25mm, 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 double-convex geometry, with radii of curvature of 25.58mm and -25.58mm for the first and second surfaces, respectively. This geometry results in a high refractive power, making the lens ideal for focusing or collimating light.
The lens is coated with MgF2, a standard coating that provides excellent anti-reflection properties. The coating is applied to both the front and back surfaces, ensuring optimal light transmission across the lens's full spectral range of 400-700nm. This makes the lens particularly suitable for applications that require high light transmission and low reflectivity, such as imaging systems, beam shaping, or laser applications.
The lens has a thickness of 1.26mm at the edge and 1.5mm at the center, providing a robust and stable structure. The back focal length is 24.5mm, which is an important parameter to consider when integrating the lens into an optical system.
