G311383000 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm Uncoated
This is a G311383000 12.7 mm Dia. N-BK7 Double-Convex Lens, characterized by a focal length (EFL) of 30mm and sourced from Qioptiq Photonics. The lens is uncoated and features a base shape of a circle, with a diameter of 12.7 mm.
The lens's geometry includes a thickness at the edge of 1.6 mm and a thickness at the center of 3 mm. The radii of curvature are R1 = 30.287 mm and R2 = -30.287 mm, indicating a double-convex design. The inner and outer radii are both 0, suggesting a symmetrical lens.
The lens is made of N-BK7, a type of borosilicate glass commonly used in optical applications due to its low coefficient of thermal expansion and excellent homogeneity. The wavelength for this lens is 587.6 nm.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. For more detailed information, please refer to the provided weblink.
