111-0206E 25.4 mm Dia. x 30 mm FL; Uncoated; Double-Convex Lens

The 111-0206E is a double-convex lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens is made of the material n-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties and versatility. The lens has a diameter of 25.4 mm and a thickness at the edge of 1.8 mm, while the center thickness is 7.5 mm.

The lens has a focal length (FL) of 30 mm, which is the distance from the center of the lens to the point where light rays converge or diverge. The radii of curvature for the first and second surfaces of the lens are 29.8 mm and -29.8 mm, respectively, indicating that both surfaces are convex. The lens has no coating, which means it is uncoated, a feature that can be desirable in certain applications where the natural properties of the glass are preferred.

This lens is suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications.
