When I am employed in a garment making factory, I have passed through the process of using simple sticker to dot laser alignment tool. Both are totally different dot measuring tools. Sometimes I need to make dot alignment at very long distance, a simple sticker is far more enough to make accurate dot measurement. Before the adoption of 50mW red dot laser alignment tool, I always have to spend a lot of time on finding correct dot targeting place, and then draw a dot on processing surface. It is very annoy job.
Without a lot of time spent on dot drawing and dot location, after connected with electric power supply, 50mW red dot laser alignment begins to make dot projection. In order to make red laser diode module more applicable for industrial dot projecting, it is always equipped with DC input power supply with operating voltage of 4V. Both laser alignment tool and DC power supply are designed with electric lines. Usually the free installation height of this red dot projecting alignment laser is controllable within 0.5 meter to 3 meters.
Comparing with those of Class IIIa laser devices, 50mW red dot laser alignment tool just belongs to high powered laser class. When users are making dot alignment with this powerful laser diode module, it is always necessary to take safety measures, such as wear proper wavelength preventing laser safety goggles. On condition that user are obeying basic laser safety measures, and making proper adjustment of laser dot projecting direction, this advanced industrial alignment laser dot can make the most satisfied dot alignment and positioning efficiently.
