Safety to Use Laser Pointer Pen


The USB laser pointer pen and the waterproof ones are also fashionable. The former refers to the product that could be used for normal day presentations. During the display, the pages could be moved up and down. Some products have the USB receiver that is usually enabled with the plug and play function, and no driver is needed. In looking out for this item, it is vital that it could support several presentation programs like MS Word, MS Excel, MS Powerpoint, ACDSee, Acrobat Reader and websites. It should also be compatible with the operating system, like Windows Vista or XP or others, of your personal computer, desktop or laptop.

It is exactly this advantage which makes laser pointer so popular but at the same time presents a safety concern. When the highly focused laser beam comes into contact with biological tissues, the intense laser beam, depending on where it lands, could cause serious burn to the tissues. In particular, human eyes and skin are most susceptible to laser injuries. Eye and skin exposures to laser beam must be avoided.

The laser pointer is cylindrical in shape, very small in size just like a pen. They are very handy and easy to store but delicate tool. The main use of laser pointers is to project a point or particular spot with a beam from distance to be shown to others like in presentations, seminars etc. Powerful laser points are used in aeronautical fields. Like, spaceships, rockets.

As these lasers are very powerful laser pointer, all latest developed arms mainly the sniper rifles are coming with red laser pointers, which help in targeting the definite point. Pointers show the aimer the exact point where the bullet will hit and it helps in achieving the desired result. There are certain precautionary measures related to use of powerful laser points, which should be strictly followed:

The naked eyes should never be brought with direct contact to lasers. It might harm the retina inside the eye. The beams when they emerge from the equipment are very powerful and might cause serious damage if made direct contact. Should be strictly watched.

These lasers should never be pointed towards other. Always, should be pointed facing towards wall or the floor. This might cause injuries to others.

These powerful laser pointers should never be repaired on own as they are made with powerful lenses which might damage if repaired on own.

In considering one particular brand, look out for the high end components, high stability beam power and output power. These three pointers are your ways to finding the perfect laser pointer pen.

The advances in laser technology application over the past few decades had made people wonder what life would be like if we had not discovered the beauty of the process. “Light Amplification by Stimulated Emission of Radiation” is a process which is now known as Laser. We can find laser in multitude of consumer products such as printer, scanner, video CD, medical equipment, laser pointer, etc. Laser has not surprisingly become our faithful servant just like pen and pencil. The use of laser pointer for teaching and presentation is very much a routine. However, how many users are aware of the potential problems associated with its use?

The laser pointer is the ultimate in style for any presentation or lecture. True 18k gold plating gives this green laser pointer an unforgettable shine, and the laser itself is as impressive and reliable as any of our regular Lyra series pointers. The highly focused green beam will be visible against projection or HDTV screens where other less powerful lasers can get washed out. This special limited edition laser makes a great gift for the person on your list who enjoys a little bit of flash in their wardrobe and wants their accessories to look as good as they do!


Just pressing one button, a presenter can clearly pinpoint to the audience the message on the presentation slide which is many meters away. The highly focused light beam generated by the laser pointer can travel a long distance without diverging and create a bright spot on the surface it illuminates. Since the beam does not diverge, it conserves very much all of its energy after leaving the barrel and before hitting the target.



Conventional laser pointer usually comes with a lo
w-powered red laser. The laser beam of the pointer is generated by a laser diode which produces the red wavelength. Since the power of the laser beam is relatively low, proper use of the pointer will not normally cause any safety concerns. Recently, a more attractive green laser pointer is available in the market. The green laser pointer has a definite advantage over the red as human eyes’ response to the green wavelength is far more sensitive than the red. The green dot appears much brighter to the audience than the red dot. However, the laser diode which produces the green wavelength is not commonly available and it takes a complicated set-up to generate the green beam. With the set-up, the power of the green laser pointer can easily go over 100mW, whereas, the power of the conventional red pointer is normally less than 5 mW.

There is no shortage of video clippings in the internet showing what a powerful green laser pointer can do and it needs no further illustration about the damages a green laser point can inflict to our eyes and skin. With the growing popularity of using green laser pointer in the classroom settings, users should pay more attention to the hazards associated with the use of green laser pointer. To ensure safe use of the green laser pointer, user should not use any green laser pointer which has a power greater than 5 mW and as a habit, never point the beam at anyone. Certainly, the use of high-powered green laser under research settings is common but use it in the classroom setting is far too risky. The use of high-powered green laser pointer for presentation and classroom teaching should be strictly prohibited.
