The irx3 Wavefront Aberrometer

irx3 Wavefront AberrometerThe irx3™ Wavefront Aberrometer is a high-precision ophthalmic diagnostic device designed for researchers in eye health and vision science.  By combining high-quality, wide dynamic range Shack-Hartmann wavefront technology with patented ocular wavefront analysis software, the irx3’s key functionalities include:

  • Wavefront aberrometer
  • Wavefront accommodation assessment
  • Autorefractometer
  • Autokeratometer
  • Infrared pupillometer
  • Retinal image, visual acuity and contrast sensitivity simulations
