114-0204E 25.4 mm Dia. x -25 mm FL; Uncoated; Double-Concave Lens

The 114-0204E is a high-quality double-concave lens, sourced from the reputable optical components manufacturer, EKSMA Optics. This lens is characterized by its concave-concave base shape and circular geometry, with a diameter of 25.4 mm and a thickness that varies from 10.2 mm at the edge to 4.8 mm at the center.

The lens is designed with a focal length of -25 mm, making it suitable for applications that require a negative focal length. The double-concave design, with radii of curvature of -26.7 mm and 26.7 mm for the first and second surfaces, respectively, contributes to its dispersive properties.

The lens is crafted from the renowned material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens an ideal choice for applications that require high optical performance and precision.

The lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. This lens is currently in stock and available for immediate purchase, with more information available on the EKSMA Optics website.
