Our mounted symmetric-convex lenses, crafted from high-quality fused silica, integrate seamlessly into LINOS Microbench and Nanobench systems. The narrow focal-length tolerances of our lenses ensure consistent system integration and reliable optical behavior.

Precision-engineered for 1:1 imaging, these lenses feature two equal radii of curvature, ensuring precise optical performance for applications requiring exact image replication.

The ARB2 NIR broadband anti-reflection coating on a fused silica provides high transmission from 725 to 1050 nm wavelength range and excellent laser damage resistance, providing a high damage threshold and reliable performance under demanding conditions.

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.
