114-0104E 12.7 mm Dia. x -12.7 mm FL; Uncoated; Double-Concave Lens

The 114-0104E is a spherical lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens falls under the category of a double-concave lens, which is a type of spherical lens featuring two concave surfaces. The lens has a diameter of 12.7 mm and a center thickness of 3.2 mm, with an edge thickness of 5 mm, providing a robust structure suitable for various applications.

The lens's effective focal length (EFL) is -12.7 mm, indicating that it is a diverging lens, causing parallel light rays to spread out after passing through it. This property makes the 114-0104E an ideal choice for applications requiring light dispersion, such as imaging systems, beam expanders, or other optical instruments.

The lens is made from the material n-BK7 Schott, a high-quality optical glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. The wavelength used for the design of this lens is 546 nm, which falls within the green region of the visible light spectrum.

This particular lens does not have any coating specified in the item data, meaning it is uncoated. However, users can request custom coatings based on their requirements, such as anti-reflective coatings, dielectric coatings, or other specialized coatings to enhance the lens's performance in specific applications.
