808nm infrared laser pointer is not a simple presentation tool the same as visible lasers. Anyway, users cannot simply used this invisible laser beam for presentation. On contrary, it is merely used separately, but always using together with other machine or devices. In practical presentation work, this IR laser is always using together with sense of infrared camera, monochrome CCD camera, or night vision equipments. Once it consists of night vision surveillance system, it can be workable for all night vision IR laser illumination work efficiently.
Not the same as common visible lasers, 808nm infrared laser pointer always gets different applications. It is not being used for formal presentation of lecture, exhibition, or speech, but just getting different applications for military targeting, night hunting, rifle shooting, night vision IR laser illumination etc. Any time users are selecting this advanced IR laser, users should always pay high attention to laser safety so as to make perfect eye protection from powerful IR laser radiations.
808nm infrared laser pointer employs very simple alkaline battery as its electric power source. Only after very simple insert of two prices of AAA batteries with correct insert direction, it will support laser pointer to get continuous IR laser beam with high beam intensity. For instance, each two pieces of AAA batteries can support at least 180 minutes IR laser light emission.
