It is spending a lot of time on prior dot positioning work with a simple sticker or laser pointer, which is not able to maintain quite long time, but also not able to avoid mistake by manual operation. When 650nm red laser diode module is getting easy connect with a DC input power supply, within wide range electric current of 100V to 240V, it is keeping work with continuous red reference dot projection. When it is supported by 3V or 9V DC input power supply, this red dot laser is keeping work within wide range output power of 5mW to 100mW, which will make highly clear and bright red dot generation for various work distances efficiently.
When 650nm red laser diode module employs 650nm red laser diode, owing to quite long developing history and quite mature laser tech application, it is not only keeping improving laser beam stability, but also getting quite low production cost in use. It is only a moderate brightness red laser beam emitting device, under correct selection of output power and proper adjustment of laser beam focus, this alignment laser is assuring moderate accuracy dot alignment for all kinds of industrial precise device manufacturing work and other scientific research works etc.
Within wide range output power of 5mW to 100mW, under continuous dot alignment work, 650nm red laser diode module gets the most important design part of APC, ACC driving circuit board. It is preventing serious electric current impacting and quite rapid temperature of laser module tube. When red laser dot alignment is processed within 8 to 10 hours per day, it is reducing possibility of red laser diode and electric driving circuit board burning out or damage. Under constant output power and electric current supply, this red dot laser maintain up to 80% laser beam stability and extremely long serving lifetime in continuous work.
