G311319331 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=150mm
This is a G311319331 lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a double-convex spherical lens, characterized by its circular base shape and symmetrical convex-convex geometry. 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 lens's effective focal length (EFL) is 150 mm, making it suitable for various applications that require long-focus lenses. The radii of curvature for the first and second surfaces are 156.22 mm and -156.22 mm, respectively. The lens does not have any inner or outer radius specified, indicating a uniform curvature across the lens surface.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. It is designed to operate at a wavelength of 587.6 nm. The lens features a Qio AR Al RALVIS AOI 45 coating on both the front and back surfaces, which provides anti-reflection properties and enhances its overall performance.
