Z-Focus Stages
Z-Focus Stages
Z-focus stages are precision motion systems engineered for accurate and repeatable vertical positioning in advanced optical, imaging, and inspection applications. Designed to maintain consistent focus with nanometer-level precision, they support both high-speed scanning and precise step-and-settle motion for applications where image clarity, measurement accuracy, and dynamic response are critical.
- Precision Z-axis positioning for focus control and vertical alignment
- Supports rapid scanning and precise step-and-settle motion profiles
- Available in piezo, linear motor, and screw-driven configurations
- Piezo-driven systems provide ultra-fast response and nanometer-scale resolution
- Linear motor stages deliver smooth, high-speed motion with long travel capability
- Screw-driven designs support higher loads and extended travel ranges
- High stiffness and low vibration for stable imaging and measurement performance
- Closed-loop feedback options ensure excellent accuracy, repeatability, and minimal drift
- Compact, integration-friendly designs for microscopes, optical systems, and automation platforms
- Ideal for microscopy, semiconductor inspection, laser processing, photonics alignment, and precision metrology applications
