When IR dot alignment work is processing for quite long time and long distance, 100mW 980nm infrared laser diode module is adopting even better thermal emitting than formal IR laser pointer device. It should be working continuously for multiple application fields, such as military IR dot positioning, surveillance, intelligence system and night hunting works etc. This infrared laser dot alignment adopts inner metal heat sink cooling system and import IR laser diode with copper material as core part, it is workable with superior nice thermal conductivity and extremely stable IR dot alignment in continuous use.
In order to get highly clear dot alignment in continuous work, 100mW 980nm infrared laser diode module passes through quite strict laser beam stability tests after its production. It passes through a series of strict laser beam stability tests, such as super rapid electric current adding test, alternative high and low temperature changing test and up to 24 hours aging preventing tests, it is able to maintain up to 80% laser beam stability under continuous IR dot alignment within 8 to 10 hours. In addition, after quite special use of glass coated lens in front of IR laser diode, this infrared dot laser always keeps work with high photoelectric ability up to 80%, thus making highly clear IR dot positioning result as long as 50 meters.
Under continuous IR dot alignment work, 100mW 980nm infrared laser diode module is generating serious IR laser radiation and thermal energy from laser beam aperture. The basic use of APC, ACC driving circuit board is preventing any possibility of laser diode and electric driving circuit board burning out or damage. After enough time leaving for infrared laser alignment tube cooling down and correct adjustment of laser beam focus and IR dot targeting direction, it makes no mistake measurement in continuous use. When it is bringing potential hurt to human eyes, it is a necessity to avoid eye exposure to beam aperture and remember to wear IR laser safety goggles until achieving satisfied measurement.
