The creation of IR detection card enables clear observing of IR laser dot projection from long wavelength IR laser pointers. 808nm and 980nm infrared laser pointers are getting longer wavelength of 808nm and 980nm. Thus IR laser detection is making special observation of IR dot when it is pointing onto the card. Different wavelength IR laser shows different color red or green laser dot on the card. If users are in need of clear observing of IR laser lights, users can get more information of IR detection card here:
