C901 17" LED Chart vision, mirror function, 2~7m, low vision:0.6~1.5m
CE
Updated:
Reduce repetition between adjacent optotypes.
File path will be initialized when entering in multimedia file list every time.
The color Ishihara images has been optimized.
Product Abstract:
■ Vedio and audio playing function: It can play the vedio and audio files stored on SD card or on U disk.
■ Support extensible plug-in unit: Users can install their own test applications to the vison chart. This fuction satisfy customer’s desire of using user-defined tests.
■ We add 0.7 and 0.9 visus values to Decimal unit, which meets the common using habit of every user.
■ Equiped with a gravity- sensor. The vision chart can adjust the direction of the picture displayed on the screen. In this way the user can get a comfortable viewing angle no matter the vison chart is vertically or horizontally placed.
■ Gamma calibration fuction is realized in the contrast sensitivity test.
■ Real time optotype random display make the test accurate and reasonable.
■ Real time adjustment of red and green test chart
