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.

How to Hold A successful Laser Show with Laser Pointers?

Laser pointers are preferred by their charming colorful laser beams. Laser enthusiasts and lovers always buy some pieces laser pointers in different colors to held laser show for indoor and outside parties. All people there can enjoy such fantastic party with those fabulous visible laser lights. But do you know how to make a perfect laser party?

1.       The output power of laserpointer should be no more than 1mW.

It is widely acknowledge that once the output power of laser pointer reaches a standard, it is harmful to human being’s eyes. No more than 1mW laser pointer belongs to Class II accordingly to laser safety grade. Laser pointers in such grade have no possibility of eye damage. Thus, people can enjoy the excited laser show without worrying about any safety problem.

What’s the most important, buy from reliable laser pointer supplier. There are many shoddy laser pointers supplied by black hearted online shop which’s actual max output power is much higher that they describe. In addition, it always has no filter to stop harmful radiation from laser pointers. One can never image how serious incident happen once using those shoddy laser pointers.

2.       All visible color’s laser pointers should be mixed together.

There are blue violet laser pointer, blue laser pointer, green laser pointer and red laser pointer in the market. Party holder should choose all of them instead of his favorite colors laser pointers only. One thing important, arrange laser players stand in different positions sequential, so as to make sure all colors are fixed together when laser show begins. Organizer can engineered various laser effects by taking good use of those visible laser beams. It would bring incredible impression to all party members once there is changeable form laser show.

3.       Hold the party at night or in dark environment.

Even laser pointer is in a bright visibility, whatever its beam can’t be seen in bright environment. One can never notice its laser beam in daytime, there is only one spot when the beam stops on object surface. But when it is in a dark night, one can easily capture the gorgeous laser line in pure and straight form. It is ideal choice to hold such party when night comes, especially in wild. All people would enjoy the high time with spectacular laser beam shining all party.

Choose 1mW and less output laser pointer in all visible colors, make a good arrangement of them in fixed color and changeable shape, it would bring an imaginable laser show for you.

The Highest Output Laser Pointer

Nowadays, many consumers ask for 5000mW above handheld laser pointer. To be honest, it is impossible to make handheld laser pointer in such a high power at present technology. But what the hell is the highest output laser pointer? I would share information with you guys as follows.

There are two kinds portable laser pointer, which are pen size and handheld laser pointer classified by their sizes. Both of them are mainly consist of laser diode, lens, cooling system and body even in different size. It is acknowledge the smaller pen size laser pointer is always in a lower output power when comparing with handheld laser pointer. Usually the output power of a pen size laser pointer is from 1mW to 300mW at most, while the handheld laser pointer is from 100mW to 3000mW. But do you know the reason? As per we know, it produces heat when a laser pointer is operating, what’s more, the higher the power, the more heat the laser pointer generates. Thus the cooling system is an indispensible part in a laser pointer so as to make a stable performance. For a low output laser pointer, a small size normal metal heat sink cooling system is enough, while it asks for a better cooling system for a higher output cooling system to disperse heat. In order to make the cooling system work well, much space is needed at the same time. So now you can understand well the reason why higher output power is in a bigger size when comparing with the small pen size lower output power laser pointer.

As above mentioned, the higher of output power the laser pointer, the more heat it produces. It is not exaggerated that the heat of a 1000mW handheld laser pointer generates in one minutes on the laser pointer body can burn one’s hand skin immediately. One can never image how powerful it is unless experience it himself.

Even there is excellent cooling system equipped into the laser body, it is impossible to tolerate the heat of a 3000mW laser pointer at most. Both the laser diode and lens would be damaged seriously at once. So next time when supplier told you they have 3000mW above laser pointer, it must be a cheater.

Laser pointer enthusiasts and lovers always use high power laser pointer for thermal and burning experiments, 2000mW 445nm blue laser pointer is powerful enough to do various applications. If it is still not enough, I am sure, 3000mW IR laser pointer in wavelength of 808nm and 980nm would satisfy your needs.

So now, one can make sure the highest power of handheld laser pointer is no more than 3000mW. 

Remember to light a high power laser pointer several seconds and takes a rest, the lifetime can be longer by doing that. And a pair of laser safety goggles is necessary when operating a high power laser pointer.

Never Let Children Play with Laser Pointer Alone

By emitting a charming visible laser beam, laser pointer brings an overwhelming trend ever since it came into the market no people can resist its magic. But one must keep in mind children less than 18 years old is not allowed to play with such gadget alone.

With the development of laser diode technology, the price of laser pointer is becoming so competitive that any person if needed can buy one online. In addition, in order to satisfy consumers’ needs, laser pointer manufactures developed high power laser pointers for entertainment, for instance, popping balloon, cutting tape and lighting matches etc, which do bring quite enjoyable and excited laser time. At the same time, the potential danger that laser pointer might brings should be noticed. Children would have no aware of danger when they are playing with them for fun excitedly, that is also the reason why there are so many serious incidents caused by them.

It is widely acknowledged when laser beam shine onto object surface, there come a laser spot, all power is concentrated on the tiny spot. Laser pointer takes advantage of the characteristic of this and being widely used in various applications. Like double-edged sword, laser pointer can cause temporary or permanent blindness once shine into human being’s eyes directly. What’s worse, it is incurable blindness once retina is burnt by high power laser pointers.

Children are curious of all new things, different with others especially those ones full of mysterious. They also prefer to dig into it to see what the hell it is themselves. For laser pointer, they want to figure out how long distance it is able to travel; whether the serious danger it might be caused is correct or wrong and another questions or views they hear of or see on the internet. They have little knowledge what laser pointer is and serious danger it can cause. The strong curiosity urges them to find answers without paying attention to anything but the “truth”. There was a girl who tried to change her eyes’ color by shining a 50mW laser pointer onto eyes, finally her eyes’ color was not changed but lose sight forever. One can never image how serious incidents happen unless he/she experience himself/herself. But the price is too much, isn’t it? Other children are using laser pointers for fun but when they are playing it too excited all warning would be ignored, by following companion, they point laser pointer at aircrafts, moving vehicles etc. 

It is not rare news that serious laser incidents caused by children every day. It is not exaggerated you never know what regretful thing would happen allowing your children play with laser pointer alone once. If he/she do curious about it, play with it under adult’s guard.

Blue Violet Laser Pointer

Blue violet laser pointer is one of the most popular visible laser pointers, which makes best result in theatrical production decoration, biomedical instrumentation, imaging, and spectroscopy etc.

Blue violet laser pointer is in the wavelength of 405nm, which owns the shortest wavelength. It is not as visible as blue laser pointer, but its special color and competitive price makes it a good uses in various applications. The laser beam emitting from blue violet laser pointer looks like violet color, the charming beam makes great decoration result for special stage design, show, and theatrical performance, which is preferred by most consumers. Due to the development of laser diode technology, the price of it is very competitive. For instance, a 5mW blue laser pointer asks for USD 149.89/piece, while a 5mW blue violet laser pointer only needs USD 59.79/piece. There is no doubt that all people can afford it and buy one if needed. 

Manufactured by 405nm laser diode, blue violet laser pointer works very stably and smoothly. There are two sizes from LaserTo, one is in pen size, the other is handheld one. Pen size violet laser pointer is mostly in a lower output power, it is from 5mW to 100mW. And handheld blue violet laser pointer is in the output power of 100mW to 500mW. Both of them are designed with best quality body and cooling system, which makes them not only in good appearance but also able to provide helpful environment when it is working. What’s more, due to the safety grade, handheld laser pointer is paid much attention to safety key. There are two security keys for it, one is in the laser pointer itself, one can’t operate it without unlocking it by the key; in addition, it is stocked in a well designed suitcase locked by another key. Other people have no chance to open it unless getting two keys together.  

Like all other visible laser pointer, blue violet laser pointer is applicable for pointing, aiming and targeting, medical treatment, scientific research, entertainment etc. High power blue violet laser pointer is the most suitable for burning experiments, one can use it to pop balloon, cut tape, burn elastic and match etc.

Blue violet laser pointer is being widely used in so many fields, one also needs pay much attention to the safety when operating it in hand.

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.
