In special work field where users are trying to make highly clear dot alignment for all night version fields, none of infrared laser pointer can be comparable with a 808nm infrared laser diode module. It is projecting invisible infrared laser beam directly from a 808nm infrared laser diode within 100mW to 400mW. The advanced use of an import 808nm infrared laser diode and metal heat sink cooling system are configured with 16mm and 26mm diameter metal housing tube.
In process of long lasting dot aligning work within 8 to 10 hours per day, a correct output power made 808nm infrared laser diode module is assuring the most reliable and stable infrared dot projection, without any light decay or blur in long lasting use. Only after its freely adjusted laser beam focus and dot emitting direction, it makes no barrier no mistake and long lasting dot alignment in long lasting time.
