Product Description

The HTSY® 980 and 8500 series optical autorefractor are advanced ophthalmic diagnostic devices built by the company on a mature technology platform. This series uses a new generation of high-resolution optical imaging system. It can capture clear and delicate retinal images, laying a solid foundation for subsequent accurate analysis. The product equipment is equipped with automatic tracking, focusing and measurement functions. It is also equipped with an electrically adjustable jaw support, which can quickly adapt to the sitting postures of different patients, making the inspection process more efficient and more comfortable. The equipment also has a built-in high-speed thermal printer. After the measurement is completed, it can automatically print and cut the inspection report. The intuitive color touchscreen interface, together with clear icon guidance, allows doctors and technicians to get started easily. It ensures each measurement is simple, fast and the data is accurate.

Treatment Mechanism

1.Advanced Optical and Imaging System

The HTSY® automatic refractometer works on the principle of high-precision Hartmann-type refractometer. It is combined with an innovative optical path design and high-definition imaging components. This ensures the capture of high-quality fundus images. With adaptive high-speed image acquisition and intelligent recognition algorithms, the system can effectively analyze various optical characteristics of the eyeball. It provides solid and reliable data for refractive calculation.
