G052309322 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-100mm 450-700nm

This is a 12.7 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, a renowned name in the field of precision optics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, especially in the visible spectrum. The lens has a negative focal length (EFL) of -100mm, making it suitable for use in various applications that require light convergence or divergence.

The lens features broadband anti-reflection coatings on both surfaces (qio bbar arb2visnbk7), which are designed to minimize reflection losses across the 450-700nm spectral range. This coating enhances the lens's transmission efficiency, making it an ideal choice for applications that require high light throughput.

The lens geometry includes a center thickness of 1.5mm, and the concave surface has a radius of curvature of -51.212mm. The lens is mounted, providing convenience and ease of use.
