If users are getting serious relying on manual labor force input and long time spending on dot positioning tool of sticker, laser pointer or other mechanical dot aligning device, it is far more enough to achieve high efficiency dot projection onto desired working surfaces as expected. In order to get quite satisfied dot measuring result with high work efficiency, it is becoming a major trend to try 5mW red dot laser module. It is projecting moderate brightness red laser light directly from inner 650nm red laser diode. After quite easy installation and adjustment of laser beam focus, this dot laser alignment makes easy and high precision dot projection onto targeting surfaces efficiently.
When dot projecting work is processing for quite long time, not the same as a formally used red laser pointer, this 5mW red dot laser module is getting different inner design part of metal heat sink cooling system. When it is giving up the use of inner alkaline battery power source, after the selection of external DC input power supply, this red laser alignment is a real industrial dot measuring device. After quite nice thermal emitting performance and easy acceptation of wide range electric current within 100V to 240V, it is applying for majority working fields and maintaining extremely stable and reliable red dot projection in continuous work.
After quite special use of glass coated lens, different from a quite simple plastic coated lens, this 5mW red dot laser module keeps work with quite high laser beam transmittance and highly clear red dot projection in close distance. It is applying for majority of working environments. However, this red laser gets specially designed glass window in front of laser beam aperture. When red laser dot alignment is processing under moisture or dust working condition, it is not affecting at all, but always keeping clear and visible enough red dot projection for both long time and close distance as well.
Under a series of quite strict laser beam stability tests up to 24 hours and basic inner design of APC, ACC driving circuit board, 5mW red dot laser module is workable with excellent laser light cycling use and intelligent feedback of increasing temperature and serious electric current. When it is keeping work within 8 to 10 hours per day, after operation by skilled users or professionals, it keeps work with high precision dot projection onto any raw material surface. Every time users are making quite easy adjustment of laser beam focus and alignment laser dot targeting direction within three dimensions, it makes no track and no barrier dot measurement perfectly.
