The S-340 piezo tip/tilt mirror from Physik Instrumente (PI) is now equipped with high-resolution strain gauge sensors. The S-340 thus achieves a resolution of 20 nrad at angles of 2 mrad about both orthogonal axes.
This large mirror is used for optics with diameters of up to 100 mm (4 inches). The resonant frequency for a mirror 50 mm in diameter, for example, is 900 Hz.
The S-340 can be operated by the new, low-cost E-616 controller. Together, they form a compact, high-performance solution for beam control and image stabilization as employed in astronomy, laser machining or optical metrology, for example.
