This is a 12.7 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, featuring an effective focal length (EFL) of 30mm and a shape defined by a spherical surface. The lens is made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and wide transparency range.
The lens's geometry includes a thickness of 1.6mm at the edge, increasing to 3mm at the center. The curvature of the lens is defined by a radius (R1) of 15.51mm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
This lens is mounted, which means it is already assembled into a mechanical structure, making it ready for immediate use in optical systems.
