G063020525 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=20mm 725-1050nm

This is a high-quality, mounted double-convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 22.4 mm and a focal length of 20 mm, making it suitable for a wide range of uses.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared spectrum, with a wavelength of 587.6 nm. The lens features a double-convex geometry, with radii of curvature of 19.248 mm on both sides. This design provides a high level of optical power and a wide field of view.

The lens is coated with a broadband anti-reflection coating, specifically Qio Bbar Arb2nirnbk7, on both the front and back surfaces. This coating reduces surface reflections and increases transmission, enhancing the performance of the lens in a variety of lighting conditions.

The lens is mounted, providing a secure and stable platform for use in optical systems. The mount includes a thread for easy integration into existing setups. The lens thickness at the edge is 1.6 mm, while the center thickness is 8.8 mm, providing a robust and durable structure.

The lens is currently in stock and available for purchase through the Qioptiq Photonics website. It is part of their Precision Optics range, specifically the Singlets category, and more specifically the Symmetric Convex Lenses subcategory.
