114-1216E 25.4 mm Dia. x -100 mm FL; Uncoated; Double-Concave Lens
The 114-1216E is a double-concave lens with a base shape of circular, designed and manufactured by EKSMA Optics. This lens is part of their spherical lens category, specifically the concave-concave subtype. The lens has a diameter of 25.4 mm and a center thickness of 3.6 mm, with the edge thickness measuring at 5.3 mm. The effective focal length (EFL) of this lens is -100 mm, making it a negative or diverging lens.
The lens features two radii of curvature, with r1 at -95.7 mm and r2 at 95.7 mm, indicating the curvature of each concave surface. The lens does not have an inner or outer radius, suggesting a uniform curvature across the lens surface.
The lens is made from UVFS Mal-1965, a material with a specified wavelength of 355 nm. This material ID suggests the lens is suitable for use in ultraviolet (UV) applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
