Never Shine A Laser Pointer Upwards

There are hundreds of aircrafts incidents caused by laser pointer all over the world every year. According to the law, it is not allowed to shine a laser pointer upwards preventing any aviation incident.

Laser pointer is a powerful light concentrated gadget which can emits laser beam for hundreds of meters distance at least due to the low divergence and bright visibility. Few people have no aware that the laser beam can travel at unlimited distance if it is not stopped by things or absorbed by air. In addition, the divergence does exist, one can't notice it until in a far away distance by checking the laser spot. Once a man points a 5mW laser pointer at an aircraft several hundreds meters away, the small laser spot would be so big that it even can illuminate the whole cabin. The higher the power, the longer distance it travels. It is also very dangerous even the distance between laser pointer operator and aircraft. The laser beam travels in light’s speed, it runs so fast that the pilot has no idea what it is, the first reaction is to avoid it from shining him; once his eyes is hit by the strong visibility beam, temporary blindness would happen, the aircraft would be lost control. One can never image how severe aircraft incident it might cause.

There are news of aviation incidents every day, some suspects shine laser pointer upwards for fun in order to see how far away distance it travels and hit helicopter by coincident, while others realize the object he is aiming is an aircraft but full of fluke mind that he can’t be found to do so. While one must acknowledge no one can escape from the advanced technology of GPS and monitoring system. The sentence by shining a laser pointer to aircraft is at least five year in prison and USD $10,000 fines. One must be fully realize that it is to put all crew in danger just by his misusing of laser pointer for fun.

Laser pointer do provide much convenience for human being’s working and life by make it more efficient and colorful, while the misusing of it also bring much harm to human’s daily life. Never shine a laser pointer upwards in purpose.

Handheld Laser Pointer

Handheld laser pointer is the kind of laser pointer with higher output power, which is mainly applicable for astronomy stargazing, laser alignment, signaling, long distance illumination, laboratory thermal and burning experiments etc.

Like normal laser pointer, handheld laser pointer consists of laser diode, inner cooling system inside it but in a bigger size so as to make sure cooling system work well for continuous work in higher power situation. The output power is at least 50mW and can reach as high as 3000mW, which is a quite powerful gadget for various applications. The laser beam emitting from it can reach a longer distance, and because of that, it is suitable for those tasks which need longer beams. In addition, there is an extra focus adjustable key in front of it, which makes it more effective to work. At the same time, preventing any potential problem it might brings, the safety is much paid attentions. At the bottom of laser pointer, there is a remote connection key. When laser pointer begins to work, it must be inserted into the laser. In addition, there is also a power switch key to make a safety guard.

One can never image how powerful the handheld laser pointer is unless operate it himself. When one holds it in hand, the confidence it would work well come into mind at once, not only because of the weight sense but also together with the Aluminum coated body. All people would fall in love with it the first time he sees it.

All handheld laser pointers from LaserTo are FDA approved ones, there has no need to worry about any quality problem.

There are both visible and invisible handheld laser pointers in the markets. Among them, high power blue handheld laser pointer is the most suitable one for thermal and burning experiments. All other handheld laser pointers make much effective wok comparing with ordinary laser pointers.

Before operating a handheld laser pointer, one must be aware that it is not a toy, protective measures must be taken at the same time. It is necessary to wear a pair of laser safety goggles, and never point at human beings, moving vehicles, aircrafts, animal etc.

Handheld laser pointer is a revolution of laser pointer, it brings much convenience for human beings in pointing tasks, scientific research, medical treatments, thermal and burning experiments etc.

Red Laser Pointer, LaserTo

As one of the visible laser pointers, red laser pointer is preferred by various laser pointer lovers and enthusiasts. It is widely used in many fields, for instance, pointing and presentation applications.

Red laser pointer is the first created laser pointer, it owns the most mature and advanced laser diode technology, thus the price of it is the most affordable one. Even it is not as bright as green laser pointer, the shining and gorgeous red laser beam attracts most laser pointer users and apply to different occasions. 

Kinds of red laser pointer,

There are two main wavelengths red laser pointer which are 635nm and 650nm ones, both of them are made from finished laser diodes. By emitting pure red 635nm and 650nm laser beams, they produce unique capability, special functionality and innovative design red laser pointer to customers. When comparing these two kinds wavelength laser pointers, one can easily find out the 635nm red laser pointer is about three times brighter than 650nm red laser pointer, while the 650nm owns lower divergence which can project for a much longer distance. For high power red laser pointer, the dot of 650nm is much perfect, and the price of is lower, on basic of that consumers would like to choose 650nm high power red laser pointer.

Uses of red laser pointer,

Both 635nm red laser pointer and 650nm red laser pointer are mainly applicable for pointing applications, people can use them in research centers, medical treat, military aspect,  pet toys and even thermal and burning experiment.

It is a good tool for class teaching, presentation and museum guiders. One can capture all people’s attention around with the small gadget in hand by pinpointing specific space no matter where he is standing.

Also, pets quite enjoy the fun of catching the moving red dot.

High power red pointer is also good at popping balloon, cutting cape, lighting match or burning plastic.

Red laser pointer is and would always be the most perfect tool for pointing and presentation aspects. One can choose suitable one accordingly.

Cross Laser Alignment, LaserTo

Cross laser alignment is the most special laser module which projects two perpendicular lines on targeted surface or objects within a limited distance. It is being widely used by those projects which asking for accurate vertical targeting and measurement.

Like other laser alignments, there are both visible and invisible cross laseralignment created by LaserTo.

Kinds of cross laser alignment,

1.532nm green cross laser alignment

Green cross laser alignment is the most visible cross laser alignment. The laser beam it emits is at least 5 times brighter than the red cross laser alignment at the same output power. By projecting two clear perpendicular 532nm green cross lines with high accuracy and precision 90 degree on targeted place, it is a very helpful tool for precise vertical positioning and measurement.

2.650nm red cross laser alignment

Even red cross laser alignment is not as visible and green laser, it is preferred by most consumers. It projects quick and moderate two 650nm perpendicular lines on a target surface.

All cross laser alignments created by LaserTo are able to provide a high precision alignment result in tasks of requiring moderate Level of accuracy integrated with adjustable focus.

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.
