L-PCC030 18 mm Dia. Plano-Concave Lens; EFL=-25mm Uncoated

The L-PCC030 is a plano-concave lens with a diameter of 18 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 features a center thickness of 1.5 mm, providing a sturdy base for integration into various optical systems.

The L-PCC030 has an effective focal length (EFL) of -25 mm, indicating its diverging nature. This negative focal length makes it ideal for use in applications where beam dispersal is required, such as in laser systems or imaging applications. The lens's concave shape, characterized by a radius of curvature (R1) of -12.92 mm, further contributes to its diverging properties.

This lens is made from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and high Abbe number. The wavelength of 587.6 nm, corresponding to the d-line of sodium, is commonly used in optical testing and calibration.

Notably, the L-PCC030 is uncoated, meaning it does not have any anti-reflective or protective coatings. While this may result in higher reflectance at the air-glass interfaces, it also means the lens can be easily integrated into various systems without concerns about coating compatibility.
