G052404322 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-100mm 450-700nm

This is a G052404322 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens is mounted and features a base shape of a circle, with a diameter of 12.7 mm. It is a double-concave spherical lens, designed with a center thickness of 1.5 mm and an effective focal length (EFL) of -100 mm, making it a powerful tool for focusing or diverging light.

The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The radii of curvature for this lens are -104.41 mm for the first surface and 104.41 mm for the second surface. The lens is designed to operate within the wavelength range of 450-700 nm, making it suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and laser systems.

The lens comes with a broadband anti-reflection coating on both the front and back surfaces. The coating, identified as 'qio bbar arb2visnbk7', is designed to minimize reflection losses and improve transmission, thereby enhancing the overall performance of the lens.
