The QFOCUS QF-50 piezo nanopositioning stage from Aerotech (Pittsburgh, PA) is designed for high-performance microscope objective and optics positioning. It offers 400 μm closed loop and 450 μm open loop travel, high speed, 0.01% linearity, sub-nanometer resolution and 4 nm bidirectional repeatability. The QF-50 offers the following specific benefits:
- It accommodates optical instruments and next-generation laser micromachining applications.
- Due to a high-stiffness mechanical design, it can outperform competitive piezo scanner offerings with larger, higher numerical aperture (NA) objectives.
- It is ideal for optical positioning applications requiring high precision and throughput coupled with long travels.
