114-1118E 12.7 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens

The 114-1118E is a spherical lens with a base shape of circle, designed and manufactured by EKSMA Optics. This lens falls under the category of a biconcave lens, featuring negative focal length, making it a double-concave lens. The lens is constructed with a diameter of 12.7 mm and a thickness that varies from 3.1 mm at the edge to 2.7 mm at the center.

The lens has an effective focal length (EFL) of -75 mm, indicating that it diverges light rays. The first radius of curvature (R1) is -71.8 mm, and the second radius of curvature (R2) is 71.8 mm, both measured from the center of the lens. The lens does not have any coating, as indicated by the empty 'coating' parameter in the item data.

The lens is made of UVFS Mal- 1965, a material specifically designed for use in the ultraviolet region of the spectrum, with a center wavelength of 355 nm. This makes the lens suitable for applications that involve ultraviolet light.

The lens is in stock and available for immediate purchase, as indicated by the 'weblink status' in the item data. For more information, including pricing and purchasing details, please refer to the vendor's website linked in the item data.
