The Marco 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.
FEATURES
Fully Automatic Measurement: Fully automatic operation (auto start, auto chin rest adjust, auto detect, auto X-Y-Z align, auto capture, auto eye transition). Voice command guides staff and patients. Manual measurement is also an option.
EyeTracking System: The EyeTracking System provides X, Y, Z axes tracking for superior alignment and focusing. The ARK-F automatically initiates measurement at the optimal alignment.
Accomodation: Accomodation testing graphs the accommodation on patients especially with pre-presbyopia symptoms, latent hyperopia and children that have near focusing difficulties.
Large Pupil Zone Imaging Method: The large pupil zone imaging method enables the measurement of wider area refraction up to 6 mm diameter and can indicate the difference between the wide area refraction and central area refraction of up to 3.5 mm diameter. These pupil diameters are measured simultaneously. The difference of the measurement allows assessment of the effect of pupil size such as a vision in dim light.
Retro Illumination: The ARK-F Autrefractor/Keratometer features retro-illumination which illustrates media opacity in both the cornea and lens
Super Luminescent Diode: Sharper and clearer images using Super Luminescent Diode (superior to LED)
Tilt LCD Screen: Large 7.0” LCD touch screen with 360° swivel & tilt capabilities for versatile positioning in corners/against walls
High Speed Printer: The printer paper can be changed easily. The data sheet is cut by an auto cutter for quick and easy detachment.
Optional Accessories:
- Optional hand-held remote control for manual measurements
- Optional control from an iPad app that provides a 1-to-1 display of the ARK-F screen
