G063029400 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=200mm

This is a G063029400 lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a mounted double-convex lens, featuring a base shape of a circle and a symmetrical convex-convex design. The lens has a diameter of 22.4 mm and a thickness of 2.4 mm at the edge, with a center thickness of 3 mm.

The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. It has an effective focal length (EFL) of 200 mm, making it suitable for various applications that require long-focus lenses. The lens's front and back surfaces are coated with qio silver ragv 45, a high-performance coating that enhances the lens's durability and optical performance.

The lens's geometry is spherical, a common shape for optical lenses due to its ease of manufacturing and good optical performance. The lens's first radius of curvature (r1) is 209.83 mm, while the second radius (r2) is -209.83 mm, indicating a double-convex design. The lens's inner and outer radii are both 0, indicating a uniform curvature throughout the lens.

The lens is designed to operate at a wavelength of 587.6 nm, a common wavelength used in various optical applications. The lens's coating and glass type are optimized for this wavelength, ensuring optimal performance.
