PLCC-25.4/64.4C 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-125mm Uncoated

This is a Plano-Concave Spherical Lens, sourced from the renowned optical components manufacturer, Laser Components. The lens, which is 25.4 mm in diameter, is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties.

The lens features a concave shape with a radius of curvature of -64.4 mm, and an effective focal length (EFL) of -125 mm. This negative focal length indicates that the lens is diverging, meaning it spreads out light rays. The lens's center thickness is 2 mm, and it does not have any coating, as indicated by the empty 'coating' field in the item data.

The lens's geometry is circular, and it is designed to operate at a wavelength of 633 nm. The 'Material ID' field indicates that the lens is made of N-BK7 Schott, a type of glass known for its low dispersion and high Abbe number, making it suitable for a wide range of optical applications.

The lens's 'Sub Type' is 'Spherical Lens (Plano-Concave)', and its 'Base Shape' is 'Circular'. The 'geometry' field provides detailed specifications about the lens's dimensions and curvature. The 'weblinks' field in the 'info' section provides a link to the datasheet of similar lenses from the vendor's website, and the 'weblink status' indicates that these lenses are in stock.
