TOPCON CORPORATION POWER SUPPLY UNIT for CV-5000 POWER SUPPLY UNIT for CV-5000 (PC EXTERNAL TYPE)

The key technique used in the easyRef Handheld Auto Refractometer is based on principle of Hartmann wave-front sensing.Light is emitted from the light source system inside the device, and then focuses on the bottom of the eye through the spectroscope and exit port, then the light is reflected back to the device,and beam through lens system and received by CCD camera. It is possible to calculate the diopter of the human eye by detecting the offset between the relative calibration light and the spot array formed by the light spot of each sub-aperture.

This instrument is applicable with stand and projection for precision measurement of visual functions such as myopia, hyperopia, astigmatism, visual acuity balance, phoria, stereoscopic vision and visual acuity amalgamation.
