G311317000 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=80mm Uncoated

The G311317000 is a 22.4 mm diameter, double-convex lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Qioptiq Photonics, is uncoated and has an effective focal length (EFL) of 80mm, making it suitable for a wide range of applications.

The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 2mm, while the center thickness is 3.5mm. The radii of curvature for the first and second surfaces are 83.536mm and -83.536mm, respectively. The lens's inner and outer radii are both 0, indicating a symmetrical design.

The lens is made from n-BK7 Schott, a type of borosilicate glass known for its low dispersion and high Abbe number. This makes it an ideal choice for applications that require high image quality and low chromatic aberration. The lens is designed to operate at a wavelength of 587.6nm.

Please note that the lens is uncoated. While this can make the lens more affordable, it may also make it more susceptible to surface reflections and scattering, which can reduce transmission and increase noise. Coatings can be applied to reduce these effects, but they may increase the cost of the lens.

The lens's parameters are as follows: a diameter of 22.4mm, an EFL of 80mm, and a shape that is spherical. The coating is not specified, indicating that the lens is uncoated.
