In those of night version precise dot measuring work fields, it is far more enough to still rely on any visible laser devices or other manual dot projecting tool at all. Under constant innovation of infrared laser diode tech, it is not the same as any other visible laser devices. Owing to its invisible laser beam and IR laser dot emission, only if this 808nm infrared dot is working with other night version machine or device, it is just able to provide users excellent infrared laser light source and IR dot alignment solution for all night version illumination work fields effectively.
The usual use of an infrared laser diode module has to work for a quite long time, although it projects the similar infrared laser beam and IR laser dot as an infrared laser pointer, however, it gets even better thermal emitting system. it adopts an internal part of an import 808nm infrared laser diode within 100mW to 400mW as its beam emitting source, together with a metal head sink cooling system inside the durable anodized aluminum alloy housing tube, this infrared dot laser has just got even sufficient space for tube cooling down and achieved highly reliable infrared dot projection within daily operating time of ten hours. 
In process of long lasting and long distance IR dot projection, without any appearance of laser light decay or blur in continuous work, under operation with a qualified glass coated Lens and a glass window in front part of laser beam aperture, this 808nm infrared laser diode module has just passed through a series of strict laser beam stability test and aging preventing tests, it is achieving high level of laser light cycling use and highly reliable infrared dot projection in long lasting use. In practical precise dot measuring work fields, it is just operating well as an accessory part of other night version devices, which also provides users excellent dot alignment solution for special application fields including military targeting, infrared laser sight, laser medical therapy, surveillance, intelligence system and high Tech work etc.
Within long extending distance, this 808nm infrared laser diode module should only be selected with correct output power and mounting correctly onto different machine or device. The special use of APC, ACC driving circuit board design has just assured its constant output power and electric current supply. It maintains long lasting and long serving lifetime IR dot projection under proper use by skilled users. It gets merely affected by increasing temperature and overheating as well. For the most important of all, it is a key issue to pay high attention to its thermal energy hurt to human eyes. Only if users are wearing correct infrared laser safety goggles and avoiding eye exposure, this infrared alignment laser just brings users easy and secured dot indication in long lasting use effectively.
