Print E-mail

mirao 52-e Electromagnetic Deformable MirrorImagine Eyes’ patented mirao™ 52-e Electromagnetic Deformable Mirror is the only product of its kind on the market today.  Only mirao has the stroke and optical quality needed to correct for the wide ranging aberrations found in eyes – even in highly-abberated and pathologically affected eyes. (click here to see an independent study on deformable mirror performance on the SPIE website)

In retinal imaging, mirao enables you to improve both the transverse and axial resolutions of today’s leading cellular imaging techniques including OCT and confocal/multiphoton microscopy.  As a component in your vision simulation system, mirao enables you to correct for aberrations and simulate the effects of various aberrations on vision (click here to see a list of scientific publications using mirao and our adaptive optics products).

Key technical specifications include:

  • 50 µm wavefront stroke
  • 52 actuators on a 15mm effective pupil
  • exceptional optical quality of 0.01 µm RMS
  • 95% linearity
  • lack of hysteresis (<2%)
  • TRIG-OUT for TTL synchronization
  • USB2 connectivity
  • ANSI-based Application programming Interface (API) compatible with Windows XP and Window 7 (x32 - x64 under evaluation)
  • Fully IEC 61010 & 1236 compliant (electrical safety and electromagnetic compatibility)

mirao 52-e comes complete with the following:

  • mirror unit
  • electronic control unit
  • CD-ROM with the API, software tools that allow the user to verify system installation and operational status, a file conversion utility (CSO-CASAO-HAS) for file sharing between our other software products, a demonstration program
    that employs each of the API’s commands
  • user documentation
  • connection cables
