G311319525 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=150mm 725-1050nm
This is a high-quality double-convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 22.4 mm and a thickness of 2.2 mm at the edge, with a center thickness of 3 mm. The effective focal length (EFL) of this lens is 150 mm, making it suitable for use in systems where a longer focal length is required.
The lens is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The curvature of the lens is symmetric, with a radius of curvature of 156.22 mm on both sides. This design ensures a wide field of view and low distortion.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly in the 725-1050 nm wavelength range. This makes the lens ideal for use in systems that operate in the near-infrared region of the spectrum.
