In various industrial precise dot measuring work fields, no matter it is pointing at close or long distance, it is operating easy and quick with an industrial stabilized device, such as a 635nm red laser diode module. It applies advanced 635nm red laser diode tech and qualified glass coated lens, cooperating with high duration metal housing tube design, it is being made into a practically used device of 635nm red laser diode module. On condition that it gets constant power source supply and proper mounting onto any other industrial device or equipment, not relying on any manual labor force input, this red dot laser just assures easy reaching, highly clear and precise red dot projection onto various working surfaces constantly. In those of high precision dot measuring work fields, no matter it is pointing at close or long distance, this 635nm red laser diode module enables freely selected output power of 5mW to 100mW. The adoption of an import 635nm red laser diode is cooperating with a metal heat sink cooling system. Different from a simple red laser pointer only used for temporary dot positioning work, in practical dot measuring work, this red dot laser always gets at least 40% laser beam stability increasing . In formal constant dot alignment within 8 to 10 hours per day, only after leaving enough time and space for tube cooling down, this dot laser alignment achieves high level of laser light cycling use and highly reliable red dot indication for a lot of raw material processing works.According to the use of high quality glass coated lens, whatever kind of working surface it is pointing, this 635nm red laser diode module is getting better performance than formal plastic coated lens. Thus there is no appearance of laser light decay or blur in continuous use. On basis of advanced use of a glass window in front of laser beam aperture, whatever kind of working surface it is pointing, this red dot laser is generating high transmittance and high intensity red laser light emission, and highly clear red dot projection within long extending distance of 25 meters and high lighting occasion etc.With the assistance of laser alignment mounting bracket, even though some of working surface it is not easy to reach, ultra compact size tube made 635nm red laser diode module makes sure of the most convenient installation, and the easiest reaching of red dot indication in constant use. It enables correct use of output power and freely adjusted laser beam focus, only after high attention to powerful laser radiation and thermal energy hurt to human eyes, this alignment laser gets high concentration and high density red laser light emission, and high level of accuracy red dot indication for all precise dot measuring work in those of industrial and high tech fields effectively.
