G311377000 12.5 mm Dia. N-BK7 Double-Convex Lens; EFL=12.5mm Uncoated

The G311377000 is a 12.5 mm diameter, double-convex lens manufactured by Qioptiq Photonics. This lens, designed for use in the visible light spectrum with a center wavelength of 587.6 nm, is made from N-BK7 glass, a popular choice for its high homogeneity and excellent transparency in the visible spectrum.

The lens features a large diameter of 12.5 mm, providing a wide field of view and increased light gathering capability. The double-convex design, with radii of curvature R1 and R2 at 11.971 mm and -11.971 mm respectively, ensures a high refractive power and a short focal length of 12.5 mm. This makes the lens suitable for applications requiring a compact, high-power optical element.

The lens has a thickness of 1 mm at the edge and 4.5 mm at the center, providing structural rigidity and resistance to deformation. The uncoated surface ensures high light transmission but may be susceptible to surface reflections. The lens geometry is circular, contributing to its robust design and ease of integration into various optical systems.
