Marco ARK-F Autorefractor/Keratometer
The ARK-F is a fully automatic Autorefractor and Keratomer with auto start, auto chin rest adjust, auto detect, auto X-Y-Z align, auto capture, and auto eye transition. Gentle voice command guides staff and patients. There is a wide area of refraction of up to 6 mm and mire rings for keratometry which objectively measures accommodation and captures retro-illumination images. The large 7.0” LCD touch screen has a 360° swivel and tilt capabilities for versatile positioning in corners and against walls. Sharper & clearer images using Super Luminescent Diode (superior to LED). Options include a hand-held remote control for manual measurements and control from an iPad app that provides a 1-to-1 display of the ARK-F screen.
