114-0218E 25.4 mm Dia. x -125 mm FL; Uncoated; Double-Concave Lens

The 114-0218E is a double-concave lens with a base shape of circular, designed and manufactured by EKSMA Optics. This lens is part of their extensive range of spherical lenses, specifically engineered for applications requiring concave-concave lenses. The lens is made from the material n-bk7 schott, a popular choice due to its excellent optical properties.

The lens has a diameter of 25.4 mm and a thickness at the edge of 4.1 mm, while the center thickness is 3.1 mm. The effective focal length (EFL) is -125 mm, indicating that it is a diverging lens. The radii of curvature for the first and second surfaces are -130.2 mm and 130.2 mm, respectively. The lens does not have any coating, as indicated by the empty 'coating' field in the item data.

This lens is suitable for use in various applications, including imaging systems, beam shaping, and other optical systems where a double-concave lens is required. The uncoated version is ideal for applications where cost-effectiveness is a priority, or when specific coating requirements are not needed.
