G063875525 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-1000mm 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 infrared spectrum.
The lens features a negative focal length (EFL) of -1000mm, 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 unique light bending properties.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, enhancing its performance in the 725-1050nm wavelength range. This coating reduces reflection and increases transmission, making the lens more efficient in its function.
The lens is mounted, providing convenience and ease of use. The center thickness of the lens is 1.5mm, adding to its robustness without compromising its optical performance.
