Infrared
laser pointer emits invisible laser beam which can’t be detected by human’s
naked eyes. By taking advantage of this characteristic, it is being used widely
in medical treatment, military targeting and shooting, scientific research,
outside night version infrared laser illumination etc.
The difference
between IR laser pointer and normal visible laser pointer,
The
most popular infrared laser pointers in the market at present are 808nm, 980nm
and 1064nm ones. One can easily find out that IR laser pointer owns longer wavelength
when comparing with the visible laser pointers, for instance violet blue, blue,
green and red laser pointer. According to spectrum, specific colors laser beam
depends on wavelengths themselves. Even IR laser can’t be detected by human’s
eyes, they do exist and can be captured by some detective devices. For
instance, night version infrared thermal imager and monitoring always use IR
laser inside it, thus it is able to capture human image on basis of temperature
of human bodies.
Owing to invisible light emitting in atmosphere, IR laser is playing a completely different part in human daily life. It is mostly used in industrial, scientific, medical treatment, military field etc. For instance, low powered 808nm infrared laser pointer equipped on night vision device will be used for near-infrared illumination which allows people or animal to be observed without being detected. Infrared laser pointer will make high efficiency illumination in all kinds of night vision, target acquisition, homing and tracking, surveillance. In addition, they can work so well even without being noticed.
Safety measures of infrared laser pointers:
The invisible beam pointing has made no people being noticed of IR laser. All people who are operating with an infrared laser should be totally understanding the hazard of IR light, and take needful measures whenever holding any infraredlaser pointer in hand. Do be cautious with this invisible beam IR laser and let it be a real night vision tool in operation.
It is no doubt that infrared laser pointer plays an important part in some specific fields. Making good use of it and be aware to be careful when operating it.
