L-PCC019 25.4 mm Dia. Plano-Concave Lens; EFL=-50mm Uncoated

The L-PCC019 is a plano-concave lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is manufactured by Ross Optical, a reputable vendor known for its high-quality optical components. The lens features a center thickness of 2.5 mm and an effective focal length (EFL) of -50 mm, indicating its diverging nature.

The lens's geometry is defined by a radius of curvature (R1) of -25.84 mm, with both the inner and outer radii being 0 mm, suggesting a planar surface on one side and a concave surface on the other. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.

The lens is designed to operate at a wavelength of 587.6 nm, which falls within the visible light spectrum. It is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may result in higher reflectivity at the air-glass interfaces, which could be a consideration depending on the specific application.
