This is a G052401331 10 mm Dia. N-BK7 Mounted Double-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which has a negative focal length (EFL) of -10mm, is designed for use in a variety of optical systems where a double-concave lens is required.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties. It has a diameter of 10mm and a center thickness of 1mm, making it suitable for use in compact optical systems. The lens's double-concave geometry, with radii of curvature of -10.669mm and 10.669mm, provides a well-defined optical path for light rays passing through it.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and improve transmission, making the lens more efficient in its intended application.
The lens is mounted, making it ready for immediate use in optical systems. The provided web link leads to the product page on Qioptiq's website, where more information about the lens, including its specifications and availability, can be found.
