G052208400 12.7 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=50mm
This is a G052208400 12.7 mm diameter N-BK7 mounted double-convex lens, with a focal length (EFL) of 50mm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is of the spherical type, specifically a convex-convex lens, and is mounted on a circular base. The diameter of the lens is 12.7mm, and it has a thickness of 2.2mm at the edge and 3mm at the center. The first radius of curvature (r1) is 51.08mm, and the second radius of curvature (r2) is -51.08mm, indicating a symmetric double-convex lens. The inner and outer radii are 0mm, suggesting a simple lens design.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The glass is specifically from the Schott glass catalog, further attesting to its quality. The lens is designed to operate at a wavelength of 587.6nm.
The lens features a coating on both the front and back surfaces. The front coating is Qio Silver RAGV 45, and the back coating is also Qio Silver RAGV 45. This coating enhances the lens's performance by reducing reflection and increasing transmission.
