Key Features

The RT500AS is LAB’s workhorse when precise movement of heavy loads is required. The high load capacity however doesn’t compromise its exquisite better than 100 nm precision. Due to its modular design it can easily be equipped with a slipring, rotary union or XY stage. The RT500AS can be offered with a custom-designed granite support for easy integration in your system.
