Model: ARK-4000
The ARK-4000 provides measurement of sphere power, cylinder power, axis, pupil distance, and corneal curvature. It offers dependable data for eyeglass fitting and clinical evaluation. With Hartmann Imaging Processing technology, the device uses an 850 nm infrared lenslet array to capture fundus reflections and calculate refractive parameters, ensuring stable and accurate results for optical shops, clinics, and hospitals.
