L-PCC038 18 mm Dia. Plano-Concave Lens; EFL=-150mm Uncoated

The L-PCC038 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 effective focal length (EFL) of this lens is -150mm, indicating its diverging nature. This means that it spreads out light rays, making it ideal for applications such as beam expansion or collimation. The lens's concave surface is defined by a radius of curvature (R1) of -77.52 mm, contributing to its unique optical properties.

The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material is particularly suitable for applications in the visible spectrum, with a wavelength of 587.6 nm specified for this lens.

Notably, this lens is uncoated. While coatings can enhance the performance of optical elements by reducing reflections, increasing transmission, or providing environmental protection, an uncoated lens can offer advantages such as lower cost and simplicity. However, users should be aware of the potential for increased reflections and reduced transmission at lens interfaces.
