BICC-25.4/50.0UV 25.4 mm Dia. x -49 mm FL; Uncoated; Double-Concave Lens
This is a double-concave lens, also known as a biconcave lens, sourced from the renowned optical component vendor, Laser Components. The lens has a base shape of a circle and is designed for use with a wavelength of 248 nm. The lens is made from fused sil mal-1965, a material known for its excellent optical properties.
The lens has a diameter of 25.4 mm and a thickness at the edge of 5.2 mm. The center thickness of the lens is 2.5 mm. The effective focal length (EFL) of the lens is -49 mm, indicating that it is a diverging lens. The first radius of curvature (R1) is -50 mm, and the second radius of curvature (R2) is 50 mm, which are typical values for a double-concave lens.
The lens does not have any coating, which means it is uncoated. This may affect its performance in certain applications, particularly where high light transmission or resistance to environmental factors is required. However, uncoated lenses are often chosen for their cost-effectiveness and simplicity.
The lens is in stock and more information about it can be found on the Laser Components website. The provided weblink leads directly to the relevant datasheet.
