G311338000 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=20mm Uncoated
The G311338000 is a 22.4 mm diameter Double-Convex lens, manufactured by Qioptiq Photonics. This lens, designed for use in the visible light spectrum, has an effective focal length (EFL) of 20mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The base shape of the lens is circular, and it features a symmetric convex-convex design. The geometry of the lens includes an edge thickness of 1.6mm and a center thickness of 8.8mm, providing a robust structure.
The G311338000 is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications. It is important to note that uncoated lenses may have higher reflectivity, which could be a consideration depending on the specific use case.
