Most of the famous Chart Panels sold in the world either by big companies are based on a general purpose personal computer: standard operating system, memory data storage on mechanical hard disk, and high power dissipation. All this will give you a reliability problem.
The VS Eye Chart is different from standard PC based chart panel
The VS Eye Chart is based on high quality, new technology and maximum reliability systems:
* Linux Embedded (to assure software stability)
* Data storage flash memory (To assure no data corruption or data loss)
* Ad-hoc developed electronic board with only 4W power consumption. (for electronic long-life and silent fanless system)
The Modern Way for Vision Testing
The VS Eye Chart is a long life reliability tool.
* 40,000 hours LCD life guarantee
The VS Eye Chart is a precise tool
* 10 years of software development with the support of ophthalmologist, optometrist and orthoptist teams.
* LCD luminance and contrast curve are calibrated by a certified body for professional contrast sensitivity measurement.
* Red and Green calibration menu
The VS Eye Chart is a versatile tool
Rotating stand for table use
Multi-user: up to 3 different users
