14PCV250-1-3 25.4 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens

The 14PCV250-1-3 is a Plano-Concave Lens, a type of spherical lens, sourced from Standa, a reputable vendor in the optical industry. This lens is characterized by its circular base shape and uncoated surface, making it suitable for a wide range of applications.

The lens has a diameter of 25.4 mm and a thickness that varies from 4 mm at the edge to 3.2 mm at the center. It is designed with a focal length (FL) of -250 mm, indicating that it is a diverging lens, which spreads out light rays. The lens's inner and outer radii are both 0, and its first radius of curvature (r1) is -104.575 mm.

The lens is made of CAF2 (Calcium Fluoride), a material with the Mal-1963 ID, and is optimized for a wavelength of 2940 nm. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum, making it a versatile choice for various optical systems.

The lens's geometry and material properties make it suitable for use in a variety of applications, including imaging systems, beam shaping, and laser applications. The uncoated surface of the lens provides a cost-effective solution, but it may be more susceptible to environmental factors such as dust and moisture compared to coated lenses.
