alignment laser

 When users are trying to make highly clear dot indication at quite long work distance, it is not easy to reach with any manual dot projecting tool, such as a simple blue laser pointer or sticker etc. On contrary, when laser tech engineer is paying high attention to long lasting and high efficiency dot measuring work, it is just a good job for users to get the chance to use a 445nm 100mW blue dot laser module. It is keeping work with high intensity and formal brightness blue laser light directly from a 445nm blue laser diode. Only if compact size tube made blue laser gets proper installation and adjustment to correct position, it just brings users good direction and the lowest price dot indication at long work distance effectively. The usual use of a 445nm blue dot laser module is different from a simple blue laser pointer. It should have to work for quite long time. The advanced use of an AC/DC adapter has just assured even larger space leaving for tube cooling down. The adoption of a
