Nidek AR-600A Autorefractor
The NIDEK AR-600 is an auto refractometer which objectively measures refractive errors of sphere, cylinder, and axis for the lens that corrects the patient’s vision into emmetropia. Weak infrared rays are used for the measurement.
This device has a main body and a measuring unit integrated on one base. On the base are a chin rest on the patient’s side and a printer on the operator’s side which outputs measured results. On the main body is a TV monitor, a control panel, and a joystick, which are used to make alignment and perform operations. The measuring unit has a measuring window into which the patient looks and where the infrared ray radiates on the patient’s eye.
The Model AR-600 Auto Refractometer is a diagnostic device that is indicated for use in the automated measurement of refractive errors of the eye.
