The 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
