The crx1™ Adaptive Optics Visual Simulator

Print E-mail

crx1™ Adaptive Optics Visual SimulatorImagine Eye’s crx1™ Adaptive Optics Visual Simulator enables you to measure, correct and manipulate the optical aberrations of eyes with extreme precision. This unique device combines high-quality Shack-Hartmann wavefront technology with a mirao™ 52-d Electromagnetic Deformable Mirror. The crx1's internal fixation target is made of a miniature monitor that allows you to stimulate the patients' vision using almost any visual test. Key functionalities include:

  • Ocular wavefront measurement
  • Adaptive-optics custom-wavefront correction
  • User-defined adaptive optics wavefront generation
  • Visual performance assessment through user-defined wavefront aberrations
  • Wavefront assessment of accommodation

The crx1™ comes complete, mounted on a translation stage, with a joystick for positioning control, foot pedal, chinrest, connection cables, detailed documentation and a medical PC with all necessary software preinstalled.
