KBX160 50.8 mm Dia. x 150 mm FL; Uncoated; Double-Convex Lens

The KBX160 is a high-quality, double-convex lens offered by MKS/Newport. This lens, with a diameter of 50.8 mm and a focal length of 150 mm, is designed for use in a wide range of optical applications. The lens is made from N-BK7 Schott glass, a popular material due to its excellent optical properties and high Abbe number, making it an ideal choice for achromatic designs.

The lens features a base shape of a circle, with a thickness at the edge of 3 mm and a center thickness of 7.224 mm. The effective focal length (EFL) is 150 mm, and the back focal length (BFL) is 147.6 mm. The radii of curvature for the first and second surfaces are 153.805 mm and -153.805 mm, respectively. The lens is uncoated, providing a cost-effective solution for applications where coating is not required or desired.

This lens is suitable for use in the visible spectrum, with a specified wavelength of 589 nm. The geometry of the lens is spherical, a common choice for its simplicity and versatility. The lens is designed to be used in a double-convex configuration, which provides a high level of focusing power.
