114-1104E 12.7 mm Dia. x -12.7 mm FL; Uncoated; Double-Concave Lens
The 114-1104E is a spherical lens with a base shape of circle, designed and manufactured by EKSMA Optics. This lens falls under the category of concave-concave or double-concave lenses, featuring two negatively curved surfaces. The lens has a diameter of 12.7 mm and a center thickness of 3.7 mm, with the edge thickness measuring 6.7 mm.
The effective focal length (EFL) of this lens is -12.7 mm, indicating that it is a diverging lens, causing incoming light rays to spread out. The first radius of curvature (R1) is -12.6 mm, and the second radius of curvature (R2) is 12.6 mm. The lens is made of UVFS Mal-1965 material, optimized for a wavelength of 355 nm.
This lens does not come with any coating, which means it is uncoated. However, EKSMA Optics offers a variety of coating options that can be added based on specific application requirements. The lens is currently in stock and available for immediate shipping. For more information and to explore other lens options, visit the EKSMA Optics website.
