CIS of WHEC
WHEC CIS can recognize invisible images by implementing various wavelengths to its light source.
In addition, by making the working distance longer, now WHEC CIS can scan a three-dimensional objects.
Reliable and high-speed authentication can be done by using visible, ultraviolet, and infrared light source.
Comparison with conventional CISNew technologies
- Change from mono (black and white) color to full color
- Development of IR and UV scanning features
- Implementation of deeper focal lens
- 1000 times faster scanning speed than 2003 models
