This is a G311320322 double-convex lens, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens boasts a diameter of 22.4 mm and a thickness of 2.4 mm at the edge, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is 200 mm, making it suitable for a wide range of applications.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The radii of curvature for this lens are r1 = 209.83 mm and r2 = -209.83 mm. The lens is unmounted, providing flexibility for users to integrate it into their specific systems.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically within the 450-700 nm range. The lens's shape is spherical, a common geometry in optical systems due to its ease of manufacturing and use.
