NIDEK ARK-1 Auto Ref/Keratometer

The NIDEK ARK-1 Auto Ref/Keratometer offers accurate refraction measurement as well as keratometry measurement with mire ring.

FEATURES

• Large pupil zone imaging method – The large pupil zone imaging method enables the measurement of wide area refraction of up to 6 mm diameter and can indicate the difference between the wide area refraction and central area refraction of up to 3.5 mm diameter.
• SLD and highly sensitive CCD – The system combining the Super Luminescent Diode (SLD) and highly sensitive CCD significantly improves measurement capability even in dense cataractous eyes.
• Optimal fogging to minimize accommodation – Fogging allows the patient to view the target clearly and minimizes the interference with accommodation even in high astigmatism.
• Keratometry measurement with mire ring – The mire ring is used to measure keratometry. It reduces eyelid artifacts.
