Product Description

The UV Fused Silica Plano-Concave Lens is manufactured from high-purity synthetic fused silica, offering outstanding UV to NIR transmission from 180 nm to 2500 nm. The concave surface design allows for negative focal length applications such as beam expansion, collimation correction, and light divergence control. With high thermal stability, low autofluorescence, and excellent resistance to environmental stress, this lens performs reliably in both high-energy laser and UV imaging systems. Each lens is precision polished and inspected to ensure minimal surface defects and consistent optical accuracy. Custom sizes, focal lengths, and coatings (UV AR or broadband AR) are available upon request to meet diverse optical system requirements.
