PLCX-25.4-206.0-C 25.4 mm Dia. N-BK7 Laser Grade Plano-Convex Lens; EFL=400mm Uncoated

This Plano-Convex lens, model PLCX-25.4-206.0-C, is a high-quality optical component sourced from CVI Laser Optics. It is designed with a base shape of a circle and is fabricated from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The lens has a diameter of 25.4 mm and a thickness at the edge of 3.7 mm, while the center thickness is slightly more at 4.1 mm.

The lens's curvature is defined by a radius of 206 mm on the convex side, with no inner or outer radius specified, indicating a plano surface on the other side. The effective focal length (EFL) of this lens is 400 mm, making it suitable for applications that require a longer focal length.

This lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide excellent performance, especially in applications where the coating might interfere with the desired optical outcome.

The lens is designed to work with a wavelength of 546.1 nm, a common wavelength used in various optical applications. It is important to note that the performance of the lens can vary depending on the wavelength used, so it is crucial to ensure that this lens is suitable for your specific application.
