Choose Proper Laser Pointer for Different Application

There are both visible and invisible laser pointers in the market, one always have no idea which wavelength/ color’s laser pointer to choose for his uses. Here, I would have a brief introduction of these laser pointers’ characteristic and guide one how to choose proper laser pointer accordingly.

On the basic of their different wavelength, laser pointers appear in both visible and invisible forms. Visible laser pointer includes violet blue laser pointer, blue laser pointer, green laser pointer and red laser pointer arranged according to their wavelengths from shorter to longer. Invisible laser pointer always means IR laser pointers in the wavelength of 8080nm, 980nm and 1064nm. Emitting a piece of monochromatic shining laser beam, visible laser pointer is most applicable for business presentation, lecture, academic teaching, military aiming and targeting, astronomy stargazing and celestial objects observation etc. While even IR laser pointer can’t be seen by human’s eyes directly, it can be captured under proper equipment and mostly applicable in industrial instrument, surveillance, and pain therapy and serotonin degradation in patients with myofacial pain syndrome under proper equipment.

Green laser pointer owns the most proximal wavelength to human being eyes’ sensibility, thus, it is the most sensible and visible to be noticed. It is at least five times brighter than red laser pointer in the same wavelength. By taking advantage of that, green laser pointer is widely used in stargazing, hunter and military aiming and targeting, signaling etc.

Red laser pointer is the first created laser pointer, which has the most mature laser diode technology and the most competitive price. It always used for indoor pointing, such as class teaching/ lecture/ business presentation etc.

Blue laser pointer is not as visible as green laser pointer, but its charming blue laser beam attracts most consumers and always being used in pointing and targeting. The high power 445nm blue laser pointer is an ideal for thermal and burning experiments. Not only because its short wavelength but also due to its gorgeous blue laser beam, one can enjoy the excited laser time when burning things. It is the first choice to pop balloon, cut tape, light match and burn paper. 

Violet blue laser pointer is the shortest wavelength laser pointer, while as its poor sensibility it is not as welcome as other visible laser pointers. Even it is easier to burn things, laser enthusiasts and lovers would not choose it when considering the laser beam.

IR laser pointers only need to be operated by professionals, which is mostly being used in scientific research, medical treatment, industrial instrument and surveillance etc.

With knowing different laser pointers’ characteristic and uses, one can choose the most suitable item accordingly.

Infrared Laser Pointer

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.

The uses of IR laser pointer,
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.

Infrared Laser Used in Military

By taking full advantage of infrared laser's characterist, invisible, nowadays IR laser pointer is used in military field more and popular, such as target designation and raging, defensive countermeasurement, communications and directed energy weapons.

IR laser means the laser which emits the invisible beam to naked eyes with the wavelength of 808nm,980nm and 1064nm. Like other visible laser pointer, IR laser also can be used as laser sight by mounting on gun and aligned to emit a beam parallel to the barrel.

And aligned laser pointers are used as laser gunsights to aim a firearm.Some militaries use lasers to mark targets at night for aircraft. This is done to ensure that "friend" and "enemy" targets respectively. A friendly target may wear an IR emitting device that is only visible to those utilizing night vision (such as pilots.) To pinpoint the exact location of an enemy combatant, they would simply illuminate the target with a laser beam detectable by the attacking aircraft. This can be one of the most accurate ways of marking targets.

At the same time, ,military forces have IR lasers to illuminate hostile targets without revealing its position as infrared laser's invisibility.This is a quite useful gadget to do defensive countermeasurement. One can see enemy clearly by wearing detectable vision device even at night time, while hostile notices nothing.

With the development of technology, weapons are becoming more and more powerful. There is no doubt that infrared laser is playing its important role in weapons.
