If noting can be observed by human eyes, in order to make clear enough line alignment under night vision illumination, it is the best solution to adopt Berlinlasers 808nm infrared line laser module. It is projecting invisible infrared laser beam and infrared laser line from beam aperture. It is equipped with qualified glass coated lens or separate crystal lens, available with selected lens degree of 10 to 110 degree, it is getting modifying laser light in type of highly straight and fine infrared laser line in distance.
When 808nm infrared line laser module is employing import 808nm infrared laser diode, within 100mW to 400mW, it obtains extremely high laser beam transmittance and generates highly clear IR line alignment as long as 100 to 1000 meters in use. The important design of APC, ACC driving circuit board prevents increasing temperature and serious electric current impacting, always protecting laser line generator from burning out or damage. Under daily IR line alignment within 8 to 10 hours per day and avoiding eye exposure to beam aperture, this infrared line laser achieves safe and free line alignment constantly.
