Physik Instrumente has introduced the S-340 Piezoelectric Tip/Tilt Platform for fast laser beam steering and image stabilization. The platform accommodates mirrors and optics with diameters up to 3 in. and can be operated in step or continuous modes. PI says the two piezo actuators and two linear variable differentiation transformer displacement sensors per axis guarantee maximum temperature stability and a <1 µrad resolution. Applications include boresight systems and active optics.
