BICC-5.0-5.5-C 5 mm Dia. N-BK7 Laser Grade Concave-Concave Lens; EFL=-5mm Uncoated

This is the BICC-5.0-5.5-C, a laser grade concave-concave lens with a 5 mm diameter, sourced from CVI Laser Optics. The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The lens is uncoated, which means it does not have any additional layers to enhance its optical performance or protect it from environmental factors.

The lens has a center thickness of 2 mm and an effective focal length (EFL) of -5 mm, making it a concave-concave lens. The first radius of curvature (R1) is -5.5 mm, and the second radius of curvature (R2) is 5.5 mm. The lens's geometry is circular, and it does not have any inner or outer radii.

The lens is designed to operate at a wavelength of 587.6 nm. It is important to note that the lens's performance may vary depending on the application and the conditions it is used in. Therefore, it is recommended to consult with the vendor or a qualified optical engineer before using the lens in a specific application.
