This is a mounted double-convex lens, type G063021322, manufactured by Qioptiq Photonics. The lens has a diameter of 22.4 mm and an effective focal length (EFL) of 25 mm, designed for use within the wavelength range of 450-700 nm. The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and versatility.
The lens features a base shape of a circle and is constructed with a double-convex geometry. The first radius of curvature (R1) is 24.406 mm, while the second radius (R2) is -24.406 mm, indicating a symmetric convex-convex design. The lens has a thickness of 1.6 mm at the edge and 7 mm at the center.
The lens comes with anti-reflection (AR) coatings on both the front and back surfaces. The coating type is qio bbar arb2visnbk7, which is specifically designed for high performance in the visible spectrum. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens is mounted, making it ready for immediate use in optical systems. The item data does not provide specifics about the mount, so it is recommended to check with the vendor for detailed information.
