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

Our mounted plano-concave lenses, made from high-quality N-BK7, integrate seamlessly with LINOS Microbench and Nanobench systems. They deliver precise optical performance for applications that require controlled beam divergence. Tight focal-length tolerances ensure consistent integration and reliable optical behavior.

The high-power, narrowband anti-reflection coating maximizes transmission at the fundamental Nd:YAG wavelength of 1064 nm and offers excellent laser-damage resistance, ensuring a high damage threshold and reliable performance in demanding environments.
