Selectable model types
Accurate refraction measurement
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.
Easy VA measurement with glare test
The ARK-1s provides visual acuity (VA) measurement. A glare source is illuminated beside the chart and the glare VA can be measured.
Simple opacity assessment with retroillumination image
The retroillumination image enables the observation of opacity of the optical media of the eye.
Patient-friendly accommodation measurement
Objective measurement of accommodation is performed with patient's focusing on a target which moves from distance to near.
Keratometry measurement with mire ring
The mire ring is used to measure keratometry. It reduces eyelid artifacts.
