PLCC-25.4-128.8-C 25.4 mm Dia. N-BK7 Laser Grade Plano-Concave Lens; EFL=-250mm Uncoated

This product is a Plano-Concave Spherical Lens, offered by CVI Laser Optics with the catalog number PLCC-25.4-128.8-C. It is a high-quality optical component designed for use in laser systems, featuring a diameter of 25.4 mm and a center thickness of 4 mm. The lens is made from N-BK7 Schott glass, a popular material for its excellent optical properties and wide transmission range.

The lens's primary curvature is concave, with a radius of 128.8 mm. This, combined with its negative focal length (EFL) of -250 mm, makes it suitable for use in applications requiring beam convergence or divergence. The lens is uncoated, which means it does not have any additional anti-reflective or protective coatings. This may be desirable in some applications where specific coating properties are not required.

The lens's geometry is circular, and it does not have any inner or outer radii, indicating a simple, uniform curvature. The lens is designed for use at a wavelength of 588 nm.
