Usually users can use a simple sticker to make dot projection, but it is quite hard to get quite accurate dot projection with such kind of gadget. Not the same as sticker, red dot laser alignment has just made quite wonderful dot projection on targeted surfaces precisely and accurate according to a clearly visible red reference dot. The noncontact red reference dot can just make the most rapid dot projection on required working surfaces in the shortest time. No matter at what kind of condition, this laser diode made product has no limitation of exact operating distance, height or targeting angle.
Once red dot laser alignment is connected with electric power supply, it will begin to make continuous dot projection on targeted surfaces continuously. In order to make dot projection more clearly and bright, this dot emitting laser alignment always adopts the finest quality 650nm red laser diode as light emitting source. The import laser diode has better performance in long time continuous dot projection. For instance, it has much longer serving lifetime than usual laser diode. Thus this dot projecting laser alignment is at least 3000 hours serving lifetime longer than usual lasers. In addition, the genuine quality laser diode has just assured super stable performance under condition of 24 hours continuous dot projection.
In order to make dot projection more stable and reliable, this dot emitting laser alignment also uses external DC input power supply. Besides its compact structure, this gadget is also easily mounted on any working surfaces vertically or horizontally. The power supply is always designed with quite long extending line of 1.2 meter. In addition, the dot laser alignment itself is also being made with electric line of about 1 meter long. As a result, whenever users are in need of making dot positioning in different working condition, this dot projecting laser alignment is just efficient enough to get the best dot measurement result on all working surfaces successfully.
