G052109331 12.5 mm Dia. N-BK7 Mounted Plano-Convex Lens; EFL=20mm
This is a G052109331 12.5 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. The lens is made of N-BK7 Schott glass, a popular choice for its high homogeneity and excellent transparency in the visible spectrum. The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex).
The lens has an effective focal length (EFL) of 20mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This makes the lens suitable for applications that require a long focal length, such as telephoto lenses in cameras or microscope objectives.
The lens has a diameter of 12.5mm and a thickness of 1.4mm at the edge, increasing to 3.5mm at the center. The curvature of the convex side is defined by a radius of 10.441mm. The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces, which enhances its light transmission and reduces reflections.
The lens is mounted, making it ready for immediate use in optical systems. The item data also indicates that this lens is in stock and available for purchase, with a direct weblink provided for convenience.
