G063851329 25.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=30mm 1064nm

This is the G063851329 model from Qioptiq Photonics, a 25.4 mm diameter N-BK7 mounted double-convex lens designed for use with a center wavelength of 587.6 nm. The lens boasts an effective focal length (EFL) of 30 mm and is equipped with a high-performance anti-reflection coating (AR) on both the front and back surfaces, specifically tailored for use with YAG lasers (qio hp nbar arhs-yag).

The lens's geometry is characterized by a thickness of 1.4 mm at the edge and 7 mm at the center, with a clear aperture of 25.4 mm. The curvature of the lens is defined by a first radius (r1) of 30.069 mm and a second radius (r2) of -30.069 mm, which are both symmetrically convex. The lens is mounted, and the inner and outer radii are not specified, indicating a flat mounting surface.
