Deformable mirrors

ALPAO Deformable Mirrors are based on continuous reflective surface motioned by magnetic actuators. 

 They feature large strokes, high dynamic motion and an excellent optical quality to meet and exceed your requirments for fast and accurate wavefront correction.

Key features

deformable mirror motion transp
hi speed deformable mirror 97 15 zernike
Large deformation 
  • • Up to 80μm optical deformation (peak to valley): to correct large amplitude aberrations.
  • • Up to 5.0μm optical deformation (inter actuator): to correct high spatial-frequency aberrations.
Highly dynamic motion:
  • • Settling time as low as 500µs at +/­-10%. 
Optical quality
  • • Active best flat as low as 7nm RMS.

Note 1: preliminary specifications

Customize your DM

  • • Other coatings: gold, aluminium or dielectric for higher LIDT
  • • Large-stroke, high speed or high optical quality options provide additional specific features (datasheet)
  • • High-stability option provides increased open-loop performances
  • • Trigger to synchronise sharply the hardware of your system

Technology

fitting simulator

This adjacent animation shows our unique technology with membrane, coils, magnets and springs.

By applying a current in the coils, the magnets are moved up and down to deform the membrane.

Let's focus on your needs:

  • • More actuators? Up to 64x64 is available.
  • • Large quantity? Ask for our low price OEM DM.
  • • Faster or larger stroke? Every parameter can be customized.
  • • A larger pitch for a larger pupil? Ask for your DM.
