The ARK-8500 Auto Refractometer & Keratometer is designed for fast and stable refractive and corneal measurement in hospitals, clinics, and optical centers. It uses a Hartmann-type optical system with high-speed image acquisition to improve measurement accuracy and efficiency.

The device supports automatic motorized focusing in horizontal, vertical, and depth directions, helping quickly find the optimal measurement position. A flip 9-inch touchscreen and built-in thermal printer with auto-cut function improve usability and workflow efficiency.

Measurement Functions:

  • Refraction (sphere, cylinder, axis)
  • Corneal curvature measurement
  • Corneal refractive power analysis
  • Pupil distance (PD) measurement
  • Pupil size detection
  • Keratometry and corneal axis measurement
  • Multi-group data storage
