114-0114E 12.7 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens
The 114-0114E 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 2.7 mm, with the edge being slightly thicker at 3 mm.
The lens's effective focal length (EFL) is -75 mm, indicating that it is a diverging lens, causing parallel light rays to spread out. The first radius of curvature (R1) is -78.3 mm, and the second radius of curvature (R2) is 78.3 mm. The lens is made of n-BK7 Schott material, a common type of optical glass known for its excellent optical properties.
This lens is designed to operate at a wavelength of 546 nm. It does not come with any coating, which means it is uncoated. However, users can request coatings based on their specific requirements. The lens is currently in stock and available for immediate purchase. More information about this lens and similar products can be found on the EKSMA Optics website.
