Shutter Slit Systems -
For Controlling Light

Piezo technology allows for precision beam control.

For Laser Optics, Spectroscopy and Switches

Shutter slit systems utilize a single piezo stack acctuator to create symmetrical an open-close motion of two slit edges. The most common market for these systems is the photonics industry where they are used for beam shaping and collimation.

The piezo-electric slit system can be equipped with a strain gauge measurement system to avoid hysteresis, creep, and temperature effects. The positioning accuracy of the piezo element with integrated measurement system is typically 0.1% or better.

The PZS series shutter slit systems are available in UHV compatible version and with different body and slit edge materials (INVAR).

Some systems offer edges made from steel, or from invar. The optional measurement system uses a strain gauge sensor.

Common applications include: optics, spectroscopy, vacuum systems, optical switches, and shutters and scanners.

System Characteristics:

  • Symmetrical movement of two slit edges
  • Driven by a single piezo actuator
  • Max opening size from 60 µm to 1500 µm
  • Nanometer resolution
  • Vacuum compatible versions
  • Optional measurement system
