G063874525 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-500mm 725-1050nm
This is a 25.4 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 and near-infrared spectrum.
The lens features a negative focal length (EFL) of -500mm, making it suitable for applications that require light convergence or divergence. The plano-concave shape, where one surface is flat and the other is curved, contributes to its light bending properties.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly in the 725-1050nm wavelength range.
The lens is mounted, indicating it is ready for immediate use in optical systems. The center thickness of the lens is 1.5mm, providing sufficient structural integrity while minimizing optical aberrations.
