Beam Tracking with Mirror Tip- and Tilting Piezostage PKS1
In biology applications a laser beam is used for cell stimulation. First the laser beam is redirected onto 2 mirrors then directed to the cells. An important requirement, to hold the laser beam onto the cell is very difficult to achieve due to thermal effects or external vibration. The position of the laser beam needs to be controlled in real-time to track the motion of the cell.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.
piezosystem jena is worldwide supplier, manufacturer and developer of piezoelectric equipment for micro and nano positioning. Our prducts are mainly used in the fields of optics, semiconductors and automation.

Objective Positioners Adapted To Meet Your Needs For Industrial Applications
piezosystem jena has extended the objective positioner series MIPOS with two new industry products.
Typically objective positioners are firmly mounted directly onto a microscope. Piezosystem also introduces two new systems, which can be screwed on a machine or rail.
MIPOS 140:
Most installed lens positioners require an undesired extension to the optical axis. The distance between the lens and the sample is shortened. This can lead to collisions between the optics and the…

Incremental Trigger Function
Trigger signals dependent on the position of the stage
Digital piezo-controllers from piezosystem jena (d-Drive and d-Drivepro) offer flexible control for customized systems such as cameras, illumination systems, optical shutters or external measuring systems.
Now, piezosystem jena can offer a comfortable trigger function.
Trigger signals can be generated dependent on the position of the stage:
• Rising edge
• Falling edge
• On both edges in the direction of movement
An additional function sends out a trigger…
