114-1212E 25.4 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens
The 114-1212E is a double-concave lens with a base shape of circular, designed and manufactured by EKSMA Optics. This lens is a spherical type, specifically a biconcave lens, and is intended for use in optical systems that require concave-concave lens elements.
The lens has a diameter of 25.4 mm and a thickness at the edge of 6.1 mm. The center thickness is 3.8 mm, and the effective focal length (EFL) is -75 mm. The first radius of curvature (R1) is -71.9 mm, and the second radius of curvature (R2) is 71.9 mm. The lens does not have any coating applied to it, as indicated by the empty 'coating' parameter in the item data.
The lens is made from UVFS Mal-1965 material, which is suitable for use with a wavelength of 355 nm. The 'Inner Radius' and 'Outer Radius' parameters are both 0, indicating that this lens does not have any special shaping beyond its basic spherical, biconcave design.
