32-966 6mm Dia. x 18mm FL; Uncoated; Double-Convex Lens

The 32-966 is a 6mm diameter, double-convex lens with a focal length of 18mm, sourced from Edmund Optics. This lens is uncoated and features a base shape of a circle, with a geometry that includes an edge thickness of 1.7mm and a center thickness of 2.2mm. The effective focal length (EFL) is 18mm, while the back focal length (BFL) is 17.26mm. The radii of curvature for the first and second surfaces are 18.22mm and -18.22mm, respectively.

The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6nm. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility. The coating is absent, which may result in higher scattering and lower transmission compared to coated lenses. However, it can be advantageous in certain applications where a specific coating may interfere with the desired optical properties.

This lens is ideal for applications that require a compact, high-performance optical element. Its double-convex design provides a wide field of view and low distortion, making it suitable for imaging systems, beam shaping, and other applications where precise light control is necessary.
