114-1220E 25.4 mm Dia. x -150 mm FL; Uncoated; Double-Concave Lens

The 114-1220E 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 designed for concave-concave applications. The lens has a diameter of 25.4 mm and a center thickness of 4.4 mm, with an edge thickness of 5.3 mm, providing a robust and stable structure.

The lens has an effective focal length (EFL) of -150 mm, making it suitable for applications that require a negative focal length. The first radius of curvature (R1) is -143.4 mm, and the second radius of curvature (R2) is 143.4 mm, indicating a symmetrical double-concave design. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.

The lens is made from UVFS Mal-1965 material, which is suitable for use in the 355 nm wavelength range. The lens is uncoated, which may be suitable for certain applications where coating is not required or desired. However, users should be aware that uncoated lenses may have higher reflectivity and lower transmission compared to coated lenses.

The lens data provided is valid and in stock, ensuring availability for immediate use. This lens is a great option for users looking for a high-quality, double-concave lens for their optical applications.
