AR-20/ARK-30 Hand Held Auto Refractor/Keratometer
Lightweight and Portable
The design, similar in size and weight to a video camera, weighs only 980g/2.16lbs, (including battery), and allows easy portability.
Compact Station
Even the docking station is compact. The footprint is only 249mm(W)x220mm(D)/9.8(W) x 8.7(D) , permitting use on a refraction table.
Data Memory for 30 Persons
Data for up to 30 persons (60 eyes) are stored in the main body. Measurement data can be printed out later.
Wireless Communication
Infrared wireless communication connects the main body to the station printer, eliminating troublesome cord connection.
Accurate and Speedy Measurement
A newly developed three meridian phase difference measuring technique is adopted to attain accurate and speedy measurement.
Auto-Shot Function
Both centering (XY direction) and focusing (Z direction) can be detected. Auto measurement starts when the eye is in the optimal position.
AI Measuring Function
Measuring frequency is determined by the reliability of measurement data. Typical values are calculated with optimum measuring frequency.
Focusing Indicator
The focusing indicator on the monitor screen shows Z-direction focusing.
Clear Monitor Display
A 2.5inch color LCD allows comfortable operation at a nonintrusive distance between physician and patient.
R/L Auto Selection
The Right/ Left (R/L) eye being measured is detected automatically. The data is automatically determined to be R/L to prevent accidental omission of measuring the other eye.
Quick Mode
Select the quick mode to rapidly measure eyes of children and patients who blink frequently.
IOL Mode Auto Selection
IOL Mode is automatically selected to measure eyes with I.O.L. (intraocular lens) after cataract operation, a condition which can possibly cause an error. Measuring is smoothly accomplished without embarrassment to the patient.
Built-in Forehead Rest
The built-in forehead rest stabilizes the instrument for easier alignment (aiming).
