114-0108E 12.7 mm Dia. x -40 mm FL; Uncoated; Double-Concave Lens

The 114-0108E 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 and a concave-concave geometry. The lens is constructed from the material n-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties.

The 114-0108E has a diameter of 12.7 mm and a central thickness of 2.4 mm, with an edge thickness of 3.1 mm. The lens's design includes an inner radius of 0 mm and an outer radius of 0 mm, with both radii being equal. The lens's edge thickness provides additional durability, making it suitable for various applications.

This lens has an effective focal length (EFL) of -40 mm, which is the distance from the lens's center to the point at which light rays converge or diverge. The EFL value indicates that this lens causes light rays to diverge, a characteristic of concave lenses.

The 114-0108E is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can improve light transmission, reduce reflection, and protect the lens surface, this particular lens is designed to provide the basic functionality of a double-concave lens without any added features.
