Bertin Alpao Deformable Mirrors (DM) 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 requirements for fast and accurate wavefront correction.
Key Features:
- Highly dynamic motion: Settling time as low as 400µs at +/10%
- Optical Quality: Active best flat as low as 7nm RMS
- Large Deformation: Up to 90 µm optical deformation (peak to valley): to correct large amplitude aberrations; Up to 5.0µm optical deformation (inter actuator): to correct high spatial-frequency aberrations
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 64×64 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.
• High-stability option? For open-loop performances.
