This is a high-quality, mounted double-convex lens from Qioptiq Photonics, designed for precision optics applications. The lens has a diameter of 31.5 mm and an effective focal length (EFL) of 50mm, making it suitable for a wide range of optical systems.
The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high transmittance in the visible spectrum. The base shape of the lens is circular, and it features a symmetric convex-convex geometry, with radii of curvature of 52.33 mm on both sides.
The lens has a thickness of 2.1 mm at the edge and 7 mm at the center. The inner and outer radii are 0, indicating a uniform curvature. The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces, enhancing its performance in specific applications.
The lens is mounted, making it ready for immediate use in optical systems. The web link provided leads to the product page on Qioptiq's website, where you can find more information and check the current availability of the lens.
