L-PCC018 12.5 mm Dia. Plano-Concave Lens; EFL=-40mm Uncoated

The L-PCC018 is a plano-concave lens with a diameter of 12.5 mm, making it a compact yet powerful optical component. This lens is sourced from Ross Optical, a reputable vendor known for its high-quality optical elements. The lens is designed with a center thickness of 1.5 mm, providing a sturdy base while maintaining a sleek profile.

The L-PCC018 features an effective focal length (EFL) of -40 mm, indicating its concave nature. This negative focal length allows the lens to diverge light, making it ideal for applications such as beam expansion or collimation. The lens's geometry is spherical, ensuring uniform curvature and consistent light bending.

The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. This material is particularly suitable for applications in the visible spectrum, as demonstrated by the lens's specified wavelength of 587.6 nm.

Notably, the L-PCC018 is uncoated. While coatings can enhance a lens's performance by reducing reflections or increasing transmission, this lens is designed to provide basic optical functionality without any additional treatments.
