G063020322 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=20mm 450-700nm
This is a G063020322 mounted double-convex lens, offered by Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 8.8 mm, with an edge thickness of 1.6 mm. The effective focal length (EFL) of this lens is 20 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a popular optical glass type known for its excellent optical properties. The radii of curvature for this lens are 19.248 mm for both the front and back surfaces, indicating a symmetric convex-convex design. The lens does not have any inner or outer radius specified, suggesting a uniform curvature throughout.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible light spectrum, specifically within the 450-700 nm range.
