The ARK-1800 Auto Focus Refractometer is designed for fast and accurate refraction and keratometry measurement in clinics, hospitals, and optical centers. It combines a hexagon prism system with a high-sensitivity CCD to ensure stable and reliable measurement results.
With an automatic focus function, the device can quickly locate the eye and complete measurement without manual adjustment. The icon-based interface and 7-inch TFT LCD make daily operation simple and efficient.
Measurement Functions：
- Refraction (sphere, cylinder, axis)
- Keratometry (corneal curvature and power)
- Corneal astigmatism measurement
- Pupil distance (PD) measurement
- Pupil size detection
- Corneal diameter measurement
- 85° angel adjustable LCD Monitor
