808nm infrared dot laser alignment is very different from those of visible lasers. It gets longer wavelength than those of visible laser spectrums, thus generating totally invisible infrared laser beam to human eyes. As a result, in practical infrared laser dot projecting works, this infrared laser module generates invisible infrared laser dot, thus only if it is being used together with those of night vision camera or other infrared laser systems, it is able to get highly visible infrared alignment dot positioning efficiently.
In various IR illumination laser dot measuring work, 808nm infrared dot laser alignment still needs to be used continuously. As a result, this infrared laser module adopts external DC input power as its electric power source. According to its proper equipped 3V, 4.2V DC operating voltage and easy connection with electric power source, infrared laser operators can easily get constant infrared alignment laser dot projection. Owing to the employment of import 808nm infrared laser diode as its laser beam emitting source, under formal laser operating rules, its operation keeps highly stable and reliable infrared laser dot targeting. The serving lifetime is much longer than common equipped infrared laser, which can be available with as long as 8000 hours.
