ビーム 安定化 システム


We offer systems for the real-time stabilization, alignment, positioning and adjustment of laser beams.
Our systems are extremely precise, fast and very stable. User interactions are not required.
They are equipped with useful operation and safety features for a fast integration into different laser setups.

With our beam stabilization systems the laser is always stabilised in the desired target position and beam direction.
Please don't hesitate to contact us. We are looking forward to assist you in selection, planning and integration.

Laser beam stabilization "Compact"

Stand-alone system for an easy installation to the laser beam path.
It is characterized by its straightforward handling and integration.
The Compact system leads to a reliable and very precise beam position and direction stability
and it compensates disturbances.
The Piezo actuated mirrors can placed at positions of existing mirrors of the setup.

Laser beam stabilization "Compact"


  • Active closed-loop control
  • Analog system core for highest control performance with lowest phase-shift
  • Highest resolution without digitizing steps
  • No user interactions required, no need for a computer
  • Precise positioning of cw and pulsed lasers
  • Also applicable for ultrashort pulsed lasers (ps, fs)
  • OEM versions available
  • Excellent price performance ratio

Detectors for the "Compact" system

All our detectors are deveoped for the perfect combination with the "Compact" system.
We can offer the ideal detector for each application and laser.
