N-BK7 Mounted Plano-Concave Lenses, ARB2-NIR

Our mounted plano-concave lenses, crafted from high-quality N-BK7, integrate seamlessly into LINOS Microbench and Nanobench systems. These lenses deliver precise optical performance for applications that require controlled beam divergence. The narrow focal-length tolerances of our plano-concave lenses ensure consistent system integration and reliable optical behavior.

The ARB2 NIR broadband anti-reflection coating provides high transmission across 725–1050 nm and excellent laser-damage resistance, offering a high damage threshold and reliable performance under demanding conditions.

ZEMAX files are supplied to assist with optical design and simulation. For customized requirements or higher-volume manufacturing, contact us to request a quote tailored to your technical specifications.
