The TT 2.5 is a 2-axis stage (Theta, Phi) with a range of motion  of 5 mrad (for each axis). The TT2.5 is the ideal tool for applications where an optical beam steering is necessary. This makes this high-speed stage a best-seller for applications such as : particle tracking, optical tweezer, beam stabilization and scanning microscopy.

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