Regulate the application of laser pointer



Everyone wants and do get a laser pointer, because they can use it for play using. Point star, burn match, play with pet, speech instruction and so on. We are surprised by its power, the shining beam release from a small pen, the beam is bright and last long. Many naughty people use it for practical joke, they point to driver, bird, even plane. They don't aware how dangerous it might leads. Recently, FBI and FAA say that it should seriously punish the people who use a laser pen to point aircraft and disturb pilot. The picture above is taking when pilot disturbed by green laser pointer.
The insignificant tiny beam can release such a huge and shining spot. To the night fly, especially in the period of taking off and landing, a laser shoot can cause an unimaginable dangerous. In fact, the power of laser pointer has underestimated by most of the public. As the grading standard of laser safety class made by FDA, only Class 1 is safe to use, it's power is less than 1mW and don't need to labeled with warning mark. To more than 1mW laser pointer or other laser device, it is reserved to label with permanent warning mark.
I also have seen a video is a man use a laser device shoot to driver across road. The beam is so bright and shot far away that driver disrupted and lost his way. This is an experiment made by police to tell people do not play your laser pointer everywhere and without restrict. Common people hardly imagine why such a tiny pen can make such a hazard. If we see the laser light directly with our naked eye, even those low power laser pointers, it is still easily to cause temporary visual damage, including glare, flash blindness and afterimage. What will happen if it points to pilot?
In general, the spot we see in PPT screen or wall is only with 5~8mm diameter. So we don't believe what kind of dangerous can this tiny spot make. Please don't forget that light will spread after a long flight. When a laser pointer shoots a mile away, it can form a bow big strong halo. This halo is enough to illuminate the whole plane cockpit, in other words, it is enough to keep pilot feel dizzy and can't see the front runway, down lamp, as well as dashboard, the horizon. Can you imagine what will happen especially at the moment of landing and adjusting the angle. So far, although there is no laser pointer crash accidents caused by laser pointer, more and more laser pointer interfere with flight case appeared. Therefore, it is urgent to control and discipline this kind of behavior.

How to Choose a Laser Pointer

Laser was used to be thought as a high tech goods that is untouchable, but now it is not only touched by common people, but also can keep a close relation with human beings.

Your choose is decided by your use, and the quality is decided by the price of course. If you do not know what aspects you should look out for, or you are not familiar with laser, it will not be easy at all for you to evaluate the different designs of laser pointer suggestions. At this situation, I will give you following brief explanation on how to select the one that is the most appropriate for your needs.

The first one you should pay attention to is look into the kind of battery they are using. If the power is not appropriate, it will influent your experiment result. Option power is often regards as a better option as opposed to the battery type. But you might keep in mind that button is not available by the air shipment.
When it comes to evaluating different laser pointer suggestions, it is essential for you to create certain that can provide you the good management over changing the laser pointer off and on. Where some items use a moving change, others use a force button.
Another point is do not ignore to check the interval that comes with these items. It is obviously that you should go for the one that provides you a much more time assurance.
While you are playing laser pointer, you should remember that the gleam of it can be very dangerous if you aim it at somebody's skin or eye, it would destroy his or her sight. So you have to be very cautious about how you are going to use these laser pointer suggestions.
Also suggest you that choose a good laser pointer store will be convenient for you, they can help you to get a suitable laser pointer as you need. Highlasers.com is a good choice for you.

Laser Safety Class



Laser safety consists of the safe design, laser use and switch of lasers to minimize the risk of laser accidents, such as eye injuries, skin hurt, light pollution and so on. It all because that even a small amount of laser light can lead to permanent eye injuries. Here are the a survey summarizes the various medical conditions caused by lasers at different wavelengths. The wavelength between 180nm to 315nm can cause inflammation of the cornea, as the sunburn. The wavelength between 315nm to 400nm caused photochemical cataract. The range from 400nm to 780nm give rise of photochemical change to the retina, retinal burn. The wavelength from 780nm to 1400nm makes cataract,, retinal burn. The laser from 1.4μm to 3.0μm are less common, be used in military or industry, this range may leads aqueous flare. As the range from 3.0μm to 1mm, this kind of laser will cause corneal burn. The above describe is about the hurt to eye, the skin is usually much less sensitive to laser light than the eye, but the excessive laser shoot can also cause the tiny or serious effect, especially the infrared laser. 

Class I  Inherently safe. It is impossible of eye damage. This is usually applied in CD player or laser printers.
Class II  Output power may be up to 1mW. This class includes only lasers that emit visible light but the infrared laser. Most laser pointers are in this category.
Class IIa  A region in the low powered end of Class II. The laser belong to this class requires in excess of 1,000 seconds of continuous viewing to produce a burn to the retina.
Class IIIa  The lasers are mostly dangerous in combination with optical instruments which change the beam diameter or power density. The direct contact with the eye for over two minutes may cause serious damage to the retina. Output power does not exceed 5mW. Many laser sights in military are in this category.
Class IIIb  Lasers in this class may cause damage if the beam enters the eye directly. This generally applies to lasers powered from 5-500mW. It can give rise to permanent eye damage within a second.
Class IV  Lasers belong to this class with the power of more tham 500mW will cause severe, permanent damage to eye and skin. This kind of laser are widely used in military, science, industry, and medical cure.
The mark of the safety class are usually marked on the surface to help you choose a safety laser pointer. In case, you need to buy a relieved laser products such as laserpointer, laser sight, laser alignment or others, you can have a surf in Highlasers.com whose products are all marked safety mark on the surface.
