G311383329 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm 1064nm
This is a G311383329 12.7 mm diameter N-BK7 double-convex lens, designed with an effective focal length (EFL) of 30mm for a wavelength of 1064nm. The lens is sourced from Qioptiq Photonics, a reputable vendor known for precision optics.
The lens is of the spherical type, specifically a symmetric convex-convex design, with a base shape of a circle. It has a diameter of 12.7mm, with a thickness at the edge of 1.6mm and a center thickness of 3mm. The lens's first radius of curvature (R1) is 30.287mm, and the second radius (R2) is -30.287mm, indicating a double-convex structure. The inner and outer radii are both 0mm.
The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The lens is coated with qio hp nbar arhs-yag on both the front and back surfaces, providing anti-reflective properties suitable for the specified wavelength.
