Beam Tracking with Mirror Tip- and Tilting Piezostage PKS1

For this task a system with two piezo-driven mirrors and two position-sensitive 4-quadrant diodes is used. The mirrors adjust a laser beam in any direction defined by the 4-quadrant-diodes. The signals are used to operate the PKS1 piezostage for stabilizing the position of the laser beam on the cell.

The regulation of the controller uses frequencies up to 100 Hz. The piezo stage needs to be 3 to 5 times faster than the frequency. piezosystem jena uses the mirror tip- and tilting piezostage PKS1. This piezo stage adjusts the direction of the mirror in milliseconds with a frequency between 300 and 1000 Hz. For a coarse adjustment the tilting platform can be moved up to +/-2 degree manually.

From a microscope to a nanoscope

In this method a cell is excited by a diffraction-limited laser source. Immediately this cell is then overlaid by another laser source. This second laser has a special feature where it has a hole in the middle, a so-called doughnut-shaped beam. The result is a prevention of the effective excitation of the cell, except in the focal spot that happens to be in the central a...

Specialized system – Piezo Micrometer Screw Drive MICI

These elements were originally developed for quality control applications in the optics industry. They consist of a piezoelectric actuator in combination with a micrometer screw drive. The user can first adjust the coarse position of the actuator with a micrometer screw, and then fine tune it with the piezo stage itself. This improves the accuracy and reproducibility of...
