L-PCC039 18 mm Dia. Plano-Concave Lens; EFL=-200mm Uncoated

The L-PCC039 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 -200mm, 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 -103.36 mm, contributes to its diverging properties.

The L-PCC039 lens is made from N-BK7 Schott glass, a popular material due to its excellent optical properties and high Abbe number. This makes it suitable for a wide range of applications, particularly where high optical quality is required. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

This lens is designed to work with light of wavelength 587.6 nm, which is within the visible light spectrum. It is spherical in shape, a common geometry for optical lenses due to its ease of manufacturing and versatility.
