L-PCC037 18 mm Dia. Plano-Concave Lens; EFL=-125mm Uncoated

The L-PCC037 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 their 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 effective focal length (EFL) of this lens is -125mm, indicating that it is a diverging lens. This means that it spreads out light rays, making it ideal for applications such as beam expansion or collimation. The lens's concave shape, defined by a radius of curvature (R1) of -64.6 mm, contributes to its diverging properties.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes the lens suitable for use across a wide range of wavelengths, specifically designed for the 587.6 nm wavelength.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical characteristics are priorities.
