Description
The GN-9900 / GNK-9900 Auto Refractometer & Ref-Keratometer is a high-performance diagnostic system engineered to provide accurate, repeatable, and efficient eye measurements. Featuring optimal automatic fogging, the system minimizes accommodation, ensuring reliable refraction results even in challenging cases.
Powered by upgraded optical technology and a highly sensitive CCD, the GN-9900 series achieves up to 30% faster measurement time without compromising accuracy. Its wide measurement range for spherical, cylindrical, and astigmatic values supports a broad spectrum of clinical requirements.
With a minimum measurable pupil size of just 2.0 mm, among the smallest available worldwide, the device performs reliably even under low-pupil conditions. The 5.7-inch color LCD display offers excellent visibility and an elegant user interface, enhancing ease of operation.
The system automatically measures pupillary distance (PD) after examining both eyes and can store up to 10 measurement values per eye, allowing clinicians to review, compare, and select optimal data with confidence.
The GNK-9900 model additionally integrates keratometry functions, enabling precise corneal curvature, refractive power, and diameter measurements for comprehensive ocular assessment.
