Marco ARK-1a Autorefractor & Keratometer
SKU: AR0NKARK1A
The Marco ARK-1a combines autorefraction and keratometry with accommodation testing and retro-illumination. Its Super Luminescent Diode technology and X-Y-Z Eye Tracking system support accurate, repeatable measurements across a wide range of patients.
- Super Luminescent Diode (SLD) for sharper images compared to LED
- Accurate data even through many cataracts
- Eye Tracking system provides X-Y-Z tracking for superior alignment and focus
- Large pupil zone imaging method (up to 6mm diameter)
