Tiny Bimorph Mirrors

There are two ideas of making small deformable mirrors: first is use of several piezodiscs, and second - to place high-density grid of control electrodes on rather small square of piezoceramics, so to make small electrodes.
  • Diameter of the mirror aperture - from 12 mm
  • Applied Voltage - from 0V to +300V
  • Stroke - up to 10 μm
  • Number of control electrodes - 18
  • Frequency range - 5 KHz
  • Hysteresis - 12 %
  • Damage threshod - for λ=0.8μm - 3J/cm², for λ=1.06μm - 20J/cm²
  • Each mirror is supplied with the electronic block of control unit, which is connected to a standard PC computer via USB port. The standard software is included.
