111-0204E 25.4 mm Dia. x 25 mm FL; Uncoated; Double-Convex Lens

This is a 111-0204E Double-Convex Lens, sourced from EKSMA Optics, a renowned vendor known for its high-quality optical components. The lens is spherical in shape, featuring a base shape of a circle, and is designed for use in a wide range of optical applications.

The lens has a diameter of 25.4 mm and a center thickness of 9 mm, with an edge thickness of 1.8 mm. The effective focal length (EFL) of the lens is 25 mm, making it suitable for applications that require a compact, high-performance lens. The radii of curvature for the first and second surfaces of the lens are 24.3 mm and -24.3 mm, respectively, indicating a strongly converging lens.

The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material is widely used in various optical systems due to its low dispersion and high Abbe number. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. However, coatings can be added based on specific application requirements.

The lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the weblinks section.
