DTT35XS new compact piezo tilt mechanism

The DTT35XS is a new piezo mechanism coming from CEDRAT TECHNOLOGIES lab in February 2002. It comes from a development for space needs defi ned with the CNES (the French space agency), and for which a first application was found in the frame of “PHARAO”. This mechanism is based on two pairs of APA35XS, Amplifi ed Piezo Actuators displaying 35 µm of stroke each, arranged in cross configuration. The mechanism allows both a defl ection of +/- 2 mrad around the X and Y axis and a vertical displacement of 35 µm in the Z direction.
