On condition that 980nm infrared dot laser alignment is getting super nice equipment of DC input power supply, within its selectable operating voltage of 3V and 4.2V operating voltage, this infrared laser module is just able to keep continuous IR laser dot targeting in continuous work. The real work of this laser diode module should be also paying high attention to powerful IR laser light since any exposure of powerful IR laser light might cause serious hurt and damage to eyes seriously.
Owing to its invisible IR laser beam emission by human eyes, this infrared dot laser alignment cannot work separately, but just being used as an accessory part. Comparing with any other type of visible laser devices, this laser diode modules gets at least 80% laser beam photoelectric transmittance ability. Although it is being used as such a low power of only 5mW, however, it is still able to work at quite long work distance, getting clear and accurate IR laser dot targeting as expected. Once this infrared laser alignment tool gets higher output power from 200mW to 500mW, it is always workable for extremely long work distance of more than 100 meters to 1000 meters in distance.
Whatever kind of output power this 980nm infrared dot laser alignment is selected, users should always be cautious enough with powerful IR laser light and avoid eye exposure to powerful light and laser light reflection in process of continuous alignment laser dot targeting work. Users should try to select a pair of 980nm wavelength preventing laser safety goggles, this infrared laser module can get perfect eye protection from any powerful IR laser light with high laser beam intensity of Class IV. When this infrared laser device is properly adjusted of its laser beam focus and dot targeting direction, users can easily get the most wonderful dot measuring accuracy precisely.
