2D MEMS Scanning Mirrors

Our 2D MEMS mirror comes in two operation principle, bi-resonant scan and raster scan for two dimensional laser scan applications. Standard mirror coating is Al for visible wavelength range applications and Au as optional coating for NIR and IR applications. Raster scan type is designed for high resolution imaging applications.

Raster scan

  • Fast axis designed for resonant operation
  • Fast axis driven by PWM voltage signal
  • Slow axis motion controllable with voltage waveform
  • Slow axis capable of point and fix angle control
  • Support HD720P progressive image display

Bi-resonant scan

  • Both axes are driven by PWM voltage signals
  • Sinusoidal motion in both axes
  • Angle controlled by PWM voltage, duty and frequency
  • 2D MEMS mirror valuation kit available
