Mounted UV Fused Silica Symmetric-Concave Lenses, Uncoated
Our LINOS® mounted symmetric-concave lenses, made from premium fused silica, are offered in various focal lengths and diameters to meet the needs of demanding UV and high-power applications. These lenses are ideal for beam expansion, divergence of collimated light, and applications requiring minimal spherical aberration and balanced optical performance. Each lens is manufactured with strict tolerances to ensure exceptional optical quality and long-term stability, using fused silica from trusted suppliers. Lenses are available mounted in a high-quality, black-anodized, engraved aluminum mount or unmounted for custom integration.
Our mounted symmetric-concave lenses integrate seamlessly with LINOS Microbench and Nanobench systems. Tight focal-length tolerances ensure consistent integration and reliable optical performance.
These lenses feature two equal radii of curvature, delivering precise optical performance for controlled beam divergence. Their fused silica construction ensures suitability for UV and high-power applications, providing a high damage threshold and reliable performance in demanding environments. Uncoated versions are ideal for broad-wavelength applications, as fused silica offers higher transmission than standard optical glass.
ZEMAX files are provided to streamline optical design and simulation. For customized specifications or higher-volume production, contact us for a quotation tailored to your technical requirements.
