G063062525 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-100mm 725-1050nm

This is a G063062525 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range. The lens's effective focal length (EFL) is -100mm, making it a powerful tool for imaging applications where a reduced focal length is desired.

The lens is designed to work within the wavelength range of 725-1050nm, which includes the near-infrared spectrum, making it suitable for various applications such as biomedical imaging, spectroscopy, and optical telecommunications. The lens's concave-concave geometry, with radii of curvature of -104.41mm and 104.41mm respectively, contributes to its double-concave nature, which is ideal for use in beam expanding or reducing applications.

The lens comes with a broadband anti-reflection coating, specifically the Qio Bbar Arb2nirnbk7 coating, on both the front and back surfaces. This coating is designed to minimize surface reflections and increase transmission, thereby enhancing the lens's performance in its intended application. The lens is mounted, making it ready for immediate use in your optical system.
