3.5" Color Screen
New full graphic 3.5-inch color LCD is 40% larger than the previous model. Clear screen design and intuitive icons are user-friendly.
Pupil Imaging Method
The HandyRef-K analyzes a wide area (Max. 4 mm diameter) pupil zone, giving measurement data representing the refractive error of the patient’s system. Small pupils (Min. 2 mm diameter) can also be measured.
SynchroScan Technology
The HandyRef-K uses “SynchroScan Technology”: Measurements start when alignment is achieved, and data is captured when alignment becomes optimal. This provides a more stable, effective, and efficient measurement.
Lightweight Design
The HandyRef-K is lightweight with excellent weight distribution. Its compact design makes it easy to hold, balance, and use with either hand.
Achieve precise measurements anytime, anywhere with a compact body design that allows simple one hand, multi-position operation. The HandyRef-K will become a reliable partner you can always count on.
Full Graphic 3.5″ Color Screen
New full graphic 3.5-inch color LCD is 40% larger than the previous model. The clear screen design and intuitive icons provide high user-friendliness. An intelligently designed button layout is also useful in one-handed operation.
SynchroScan Technology
Measurements start when the alignment starts, and locks in the data when alignment becomes optimal as a measurement value. Accuracy is further enhanced with the pupil zone imaging method which analyzes a wide area (Max. 4mm diameter) pupil zone, giving measurement data representing the refractive error of the patient’s system.
SLD/CCD Imaging Technology
The HandyRef-K Portable Ark utilizes super luminescent diode (SLD) amp; a highly sensitive CCD. A Super luminescent diode (SLD) light source provides a sharper and better defined ring image compared to the conventional LED. The highly sensitive CCD camera detects the image even if the fundus reflection is weak due to media opacities.
Portable Base Unit
By using the portable stand, the HandyRef-K can be used as a desktop device. An integrated printer with auto cutter function is included. By using IR or wireless LAN (WLAN) connection, measurement data can be printed even if the main body and station are separated.
