The TT2 is a 2-axis stage (Theta, Phi) with a range of motion  of either 5 mrad or 10 mrad (for each axis). It is the ideal tool for applications where optical beam steering is necessary. This makes this high-speed stage a best-seller for applications such as: particle tracking, optical tweezers, beam stabilization and scanning microscopy.

This nanopositioner is part of our high-speed product line (High power controller available). High speed scan (500Hz) and step response time shorter than 2ms are possible with the High power controller.
