 Laser harmful to the skin Alerter l'administrateur Recommander à un ami Lien de l'article 

Bright Light Hazard
At around 150 milliwatts, the beam from a High power green laser pointers can be felt on the skin, depending on the beam focus, skin color (absorption), etc. At roughly 500 milliwatts, the laser's beam begins to be a skin burn hazard if the person is within a few meters of the beam.
Incidentally, even powerful industrial Laser Pointer cannot cause deep burns, severed limbs, gun-type injuries or other effects seen in science fiction movies. While multi-watt laser beams are definitely serious eye hazards, they are ineffective at causing incapacitating body injuries.
A power of 50 milliwatts is probably the maximum needed power for almost any laser pointing use.
For seeing the laser "dot" on a wall or surface indoors or in dim light, 5 milliwatts of green is fine. The most demanding general-use pointing application is for pointing out stars (NOT airplanes!!), when it is necessary to see the beam in mid-air. It takes more power to see the beam than the dot. For this use 5-25 mW should be fine, with a maximum of 50 mW for use in a large group with clear air (few particulates) in an urban environment.

If you like to pop balloons, ignite matches, or put the 50mw Green Laser Pointer Pen through textured glass for a private light show in your home, you may want a more powerful laser. But this is no longer a POINTER application.
Fortunately, wearing laser safety glasses or goggles can protect the eyes from the risks that lasers pose. The U.S Occupational Safety and Health Administration require staff to wear laser safety glasses or goggles when operating or around lasers that are Class 3b and Class 4. Class 3b lasers are lasers that powered from 5 to 500 milliwatts and Class 4 laser pointer 3000mw have output powers of more than 500 milliwatts. These laser safety glasses and goggles provide protection from reflected laser light and direct beam exposure. Laser safety eyewear is available for different wavelength ranges and for specific types of lasers. It is recommended that you find out the class of the laser you are working with as well as the appropriate wavelength range to ensure the best possible protection.
We can't emphasize enough how important it is to protect your eyes and yourself from the harmful effects of laser radiation. Remember, the damage done to the eyes from laser radiation exposure can be permanent!

 Safety Precautions laser pointer Alerter l'administrateur Recommander à un ami Lien de l'article 

People often go to theLaser Pen Shops‎ to buy laser pointer, but ignore their safety.
For star pointing, green is best. The human eye sees green much better than the same amount of red or blue, so a 5mW green laser appears to be 5 to 10 times brighter than a 5mW red laser.Looking at a green beam in the sky should not adversely affect night vision. To keep your night vision, avoid looking directly at the laser dot on a nearby or light-colored surface.

20mW Green laser Pointer are used as cat toys, sights for firearms, tools for optics experiments, to play with, and for presentations. They have frequently been used to pull pranks, some of them dangerous. When shined in the eyes, they can temporarily impair vision, cause the person to see spots, and in rare cases, even damage the retina. Some people have shined them into the eyes of airplane pilots, truck drivers, musicians, and others appearing onstage, causing problems with their vision. For this reason, health agencies have issued strong warnings against the use of laser pointers for mischievous purposes, and these devices are often forbidden from concert halls and sporting events. It is illegal to shine a 50mw Laser Pointer Pen at a police officer, for example.

There are at least two potential consumer uses for laser pointer 3000mw outdoors:
Pointing out stars in the sky: This needs to be done with caution It is an application that requires relatively strong lasers, so that viewers can see the beam shaft (not just the end dot) Further, the beam is aimed at glowing objects. in the sky. Because these glowing, point-like objects could be aircraft, outdoor laser users need to be careful.
Dispersing birds: does not recommend that ordinary consumers use lasers to scare away unwanted birds The right type of laser with a wide, low-powered beam is not available so there are too many potential safety problems for the birds, for the laser user,. . and for bystanders Also, there is a chance of accidentally having the beam be on or near an aircraft.this is illegal in many countries and jurisdictions Finally, some species of birds may be only temporarily repelled by lasers; after a few minutes or within a day, studies indicate they will return.

Some nations have worked on superpowered laser pointers as antipersonnel weapons, but a U.N. resolution adopted in 1996 forbids their use in warfare. These lasers, not always above the blinding threshold, are often referred to as "dazzlers."

 Laser Pointer lovers Alerter l'administrateur Recommander à un ami Lien de l'article 

You may need a Blue Laser Pointer 10000mw, violet or UV laser for this to be really effective though – red and green laser 2000mw don't work so well. In this case, the technique has been been combined with an Arduino that reads tweets!

Most consumer uses -- other than killing aquarium growths -- don't need more than 5 milliwatts (the traditional U.S. maximum for lasers sold as pointers). So why do some people buy handheld lasers that are 25, 100, or
laser pointer 200mw?

One reason is that there are laser enthusiasts who enjoy experimenting with lasers. They can create homemade Green Star Laser Pointer 10mWshows, they can do experiments involving burning or engraving materials, or they may like popping balloons or popcorn kernels with light. A New York Times article quotes an 18-year-old enthusiast as saying, "You learn so much in a hobby like this: electronics, soldering, physics. And you learn about light, you learn about optics. You also learn a lot of mechanical things."

Combine a laser tripwire with multiple trip points, multiple lasers, lots of mirrors, and you'll have one of the coolest Halloween haunted houses in the neighbourhood. A smoke machine is essential, as is keeping all those mirrors in alignment.

 laser pointers can make the work a lot easier Alerter l'administrateur Recommander à un ami Lien de l'article 

Yellow 50mw Laser Pointer can make the work a lot easier. When pointing out construction details, using a laser pointer 300mw is a convenient way to get the message across without any extra effort.
The range of a laser pointer may also be understood as the maximum distance from which the spot on the screen can be seen. That kind of range is normally not limited by the beam divergence but by the overall optical power (apart from the wavelength and level of ambient light), since the issue is not the comparatively minor divergence on the way from the 5in1 30mW Green Laser Pointer to the screen, but rather the huge divergence of the scattered light on the way back. Therefore, someone standing next to the illuminated screen would easily see the spot when it is already hardly perceivable from the position of the laser pointer.laser pointer
Unlike the beams of red or blue lasers, the beam of a Green Star Laser Pointer 10mW is actually visible.Hight power green laser pointers well suited for stargazing because spectators can see the beam going all the way from the laser pointer up to the star at which it is pointing. Users can take their laser pointers in hand, or even attach them to telescopes, in order to align the telescopes with certain stars.

  The beam can be point out stars Alerter l'administrateur Recommander à un ami Lien de l'article 

An astronomyLaser Pointer Blue 30000mw looks much like its regular red cousin on the outside. It is shaped like a thick pen. The beam of an astronomy 20000mw laser pointer, however, is green and about 60 times brighter than the red version. The curious properties that makes these pointers extraordinary is that the beam creates the illusion to the human eye that it is stopping at the object toward which it is pointed. The beam can be followed from hand to sky to accurately point out objects as small as stars.

The standard for an astronomy laser pointer is 5 milliwatts (mW) of power and a laser wavelength of 532 nanometers (nm). Higher wattage pointers, up to 500 mW are available, but are not always safe to use. The technology used to emit a laser of this power and frequency is more complicated than the common red type. Because a direct diode would cost thousands of dollars, it is necessary to mechanically and electronically convert a laser beam of a frequency that can be cheaply produced. The extra technology makes the astronomyGreen Laser Pointer 3000mw

more expensive than the red pointer.

10000mW 532nm green laser pointer can often be found in office supply stores and electronics retailers. They can also be found by shopping on Internet. There, they will find the Laser Pointers category.In addition, the laser colors available on Internet include red, green, blue, purple, and yellow. Buyers who are in the market for ultra-powerful lasers can also find a variety of suitable safety glasses in the laser pointers category. As a result, Internet provides buyers with everything that they will need to safely use a wide range of laser pointers.
