Motorized Focus Drives

Automated process flow within microscopy not only often requires motorized X- and Y-axes but also an automatic adjustment of the Z-axis. In order to create a complete system that is as economical as possible in such cases, various systems are available for subsequently fitting microscopes with motorized focus drives.

Piezo Z-Stage

The Märzhäuser Piezo Z-stage enables quick and high-resolution sample positioning. Focusing is achieved by moving the sample dynamically and precisely along the optical axis, adjusting within a few milliseconds and with accuracy within nanometer range.
The large, free aperture is designed for a variety of sample holders, ranging from a slide up to microtiter plates.
The Piezo Z-stage is equipped with position sensors to achieve high position stability and repeatability.
