114-1108E 12.7 mm Dia. x -25 mm FL; Uncoated; Double-Concave Lens

The 114-1108E is a spherical lens with a base shape of circular, designed and manufactured by EKSMA Optics. This lens falls under the category of a biconcave lens, featuring negative focal lengths and a double-concave structure. The lens has a diameter of 12.7 mm and a thickness at the edge of 4 mm, while the center thickness measures 2.8 mm.

The lens's effective focal length (EFL) is -25 mm, indicating its diverging nature. The first radius of curvature (R1) is -24.2 mm, and the second radius of curvature (R2) is 24.2 mm, which are typical values for a double-concave lens. The inner and outer radii are both 0 mm, suggesting that the lens has no peripheral features or additional coatings.

This lens is made of UVFS Mal-1965 material, specifically designed for use in the wavelength of 355 nm. The lens does not come with any coating, which may affect its performance in certain applications. However, its uncoated state provides a cost-effective solution for users who do not require additional surface treatments.
