Currently there is a video on YouTube showing a pointer shone at a police helicopter – can you believe anyone would be so stupid? I sincerely hope they were caught and they had the book thrown at them.

This is what I mean when I say that a few can spoil things for all the rest.

Used sensibly these pointers can be very useful as well as a fun thing. Think of how useful an item it would be if you liked to go hiking in wilderness areas. I think you could safely say, as long as your battery was fully charged, that you would never be lost.

If you did find yourself in this situation at least it would give the search and rescue teams a direction to follow if you displayed your beam.
To use a pointer this way is very useful and is a good safety factor.

These pointers come in a huge variety of power levels, 15mW, 35mW, 55mW, 75mW, 95mW, 125mW and 150mW. There are other strengths but I don’t think they are actually known simply as ‘pointers’.

Naturally the strength you choose to buy depends upon what you intend to use the pointer for. Are you interested in astronomy? Think of how you can highlight the stars, how you are going to be able to pick out particular stars to study.

When you decide that you would like to buy one of the green laser pointers there are many different prices you can pay. It will pay you to study all the products that are available to you, either online or offline, before you buy.

You are going to be looking at quite an expenditure therefore you need to be sure that you are going to get the one you want, before you pay your money out. It would be an expensive mistake to make if you bought one and found that it was not suitable for your requirements.

Some suppliers actually give you additional gifts such as LED light ball point pens, liquid filled LED Flash Lights, all sorts of things including stylish key chains and powerful torch lights.

Do your homework well and you could end up with a load more goodies than just the laser pointer.

On the downside unfortunately is the situation that these laser pointers can pose quite a serious risk to children who have been allowed to play with one, unsupervised. Their eyes are at risk concerning burns from high-powered pointers.

Children are never going to be as careful as they should be, they just don’t think ahead and this is why children should always be supervised when using a laser pointer.

Some of the damage can clear up, but not in every case and some residual damage can remain, and can degenerate to further sight loss in later years.

It is essential that children and adults alike realize that these green laser pointers [or other colors] are not really toys and should always be treated with the utmost caution to avoid any accidental damage to the users eyesight.

Red ones are fine but they are nowhere as bright as the green, in fact it is something like fifty times brighter. Plus everybody who has a laser pointer already probably has a red one.

It seems that red laser light will only appear as a red dot in dark conditions but not so the green, it stands out as a full green beam even in the daylight. The wavelength of the green is 532 nm.and this beats a 650nm red laser hollow.

This means that the green beam is great for pointing out stars and constellations etc. it can be used as a real pointer not just a dot which you could easily lose sight of. This would be especially useful if you were an amateur astronomer.

I know this is basically just a cool dude sort of thing, but there surely is a use for it regarding safety. I am thinking of when people go out walking in hills or mountains or anywhere away from civilization and they get lost. How easy it would be to find them if they had a laser [especially a green one]. It would cut down searches dramatically I would say. Of course you would have to make sure you had plenty of spare batteries to keep the laser pointer working.

The real and original use of these pointers was during lectures in auditoriums. Or perhaps pointing out something on a building or building site.

When you use a laser pointer in this context you are governed by Health and Safety legislation and they restrict usage to models with an output of just 1mW of laser light. Each country has it’s own rules and regulations regarding the use of these laser pointers in a public arena.

green laser pointers are known to produce quite an amount of infrared radiation and this can be quite dangerous to the human eye if viewed without adequate eye protection. However, there are high quality laser pointer which have an IR filter built in. Cheaper green lasers may not have this IR filter because it costs more to include this.

Nowadays people buy them to have fun popping balloons, lighting matches to light cigarettes even safety matches can be lit this way. You could even put on your own laser show if you had different colors.

It is possible to get models which are re-chargeable which is definitely more convenient than constantly having to buy new batteries.

Whilst these laser pointers are fun you should always use your responsibly. You should think of how far the beam carries and if you aimed it at a car driver you would distract him, and obviously the same applies to aiming the beam at an aircraft.

The beam can damage a person’s eyes if directed at them and at the very least distract them from what they were doing. I was reading about a cricketer who had a beam directed at his eyes when attempting a catch – which he dropped! That definitely is not cricket – using a laser beam in that way!!

Check out what is available before you spend your money – there are many cheap models around but they are made from inferior materials and will not last as long. It might be more prudent to spend a bit more and get a product which will last longer.

So – have fun but do not use your laser pointer green, red or whatever color irresponsibly.

This is exactly how it should be used primarily, to make something you are looking at stand out as in the night sky for astronomers or when you are out of doors and need to point to something in the distance. The lower strength is good for business or as a teaching tool for pointing in auditoriums.

There are quite a few different colored laser pointers available from red, red/orange/green/blue and yellow. Of these the green is the brightest.

The reason for this is that the human eye is most sensitive to the lower colors of the spectrum and green is one of those. Therefore it appears a huge amount brighter than the other colors. The green laser module will appear significantly brighter than the red of the same output.

There is another color now available blue/violet which is also another very bright beam.

A green laser pointer of 5mW strength with a wavelength of 533nm will be brighter than say a red 5mW at 640nM.

Output is measured also in nanometers [nm] as well as mW. A nanometer is defined as being a metric unit of length equal to one billionth of a meter.

30mW is regarded as astronomy and military grade of strength.

A 200mW green laser is visible for 80 miles.

A laser pointer can be expected, with sensible use, to have a life expentancy of more than 8,000 hours, that is the pen itself not the batteries of course.

Safety is a prime consideration when using a laser pointer. When these pointers were firsts introduced it was known that a 1mW power [class 2 laser] was quite safe because if you just blinked you gave your eyes enough protection. That is not to say that even this strength cannot produce retinal injury. If for some unknown reason a person overcame their natural tendency to blink and stared at the beam they could definitely bring about some sight damage.

If you were looking directly at a laser beam which was a mile away it would appear to you as though you were looking at a 100W bulb which was only 100 feet away. That would not be comfortable and I would think that normally a person would blink or turn their eyes away from such a bright light. This you need to for the safety of your eyes.

Most people have had a red laser pointer but now you need to have a green laser pointer to be seen as up to the minute and cool.

This green pointer is about 50 times brighter than a red one and is definitely a lot more noticeable.

There are so many different types and brands of green laser pointers that I couldn’t list them all here and quite a few use the ‘II’ in their product description.

One of these is advertised as having ‘an insanely bright beam that is visible for 60 miles’ – that is quite a claim!

The differences seem mainly to be in the looks of the pointers and their cases.
Most of these pointers have a range of over 1000 yards in daylight or more than two miles at night.

The green laser pointer II can be such a help when you are studying the stars, as in astronomy. The pointer helps to pick out the ones which are not so easily recognised.

These laser pointers are a great help also in an educational application. When teaching in a large auditorium it is essential that the students are able to determine just what the tutor is indicating. A green laser pointer II is a very practical solution, nobody could doubt where you were pointing when using one of these green laser pointers.

Laser pointers are used extensively by the military. Many weapons have one of these devices attached to it to enable them to focus an attack on a very specific point in the distance. When the target is also moving, the pointer greatly assists in hitting the target.

Even if you are not in the military but belong to a gun club a laser pointer fixed to your rifle is going to greatly enhance your chances of hitting your target.

There are fun applications also, all the usual things like bursting balloons, lighting matches, cutting through lightweight plastic packaging etc.etc.

Perhaps you enjoy putting on a light show. If a few of you get together you could put on quite a show.

Whatever else you do with this pointer, never ever point it at aircraft. Apart from the possible danger you are possibly going to provoke you could also get yourself into deep trouble with the authorities.

Never point it a person, especially round the eyes, or animals. Always remember that lasers burn so they cannot do anything good to your eyes!

It has power enough to be able to burn through black electrical tape so it needs to be handled with care. To point this indiscriminately at people or animals would be lunacy.

I read a comment from a person who uses laser pointers on a regular basis, his comment on the 50mW laser point was ‘fun till you’re blind’. I don’t really know if this indicates that constant use of a 50mW output pointer would damage your eyes, but I think that with the appropriate protective glasses you would be OK.

Unfortunately people who love having these powerful lasers are not as careful as they might be in wearing safety glasses. Prolonged exposure to this output of green laser beams can cause damage to the vision.

It is of perfect strength to be useful for outdoor trekking or exploring. Structural engineers would find it extremely useful I am sure, plus law enforcement personnel. 50mW is known as ‘military grade’ and usually is built to withstand all weather conditions.

It is not recommended that a laser with an output of over 5mW be used as a pointer in educational or business situation, you just don’t need power more than 5mW for this purpose.

Many people think that these more powerful laser pointers should be banned but that would be impossible now because they are used in so many areas such as astronomical, medical, military, laboratory and for many other legitimate purposes.

Just a short time ago in 2007 the FBI caught a girl pointing a laser at an aircraft which was in use. Even though manufacturers always point out safety measures for use, many people just ignore these suggestions and act totally irresponsibly regardless of any danger they might cause other people. This is totally unacceptable and I do believe that anyone caught using their laser pointer in a dangerous manner should be made to pay in some way.

In California it is a misdemeanor to shine a laser pointer at a person who then feels they are at risk. Also in California it is a felony to shine at an aircraft, so be warned!

Having said that it would be a pity to deprive genuinely careful users of their fun. Perhaps careful users could keep an eye on others so that they should not get a bad name because of the stupid few.

even children would be able to make out what you were pointing at if you were attempting to educate them about the stars. If you were involved with any sort of youth activity like the scouts this would be a valuable tool to point out anything that you wanted to talk about.

The laser pointer is a good teaching tool but remember to use it just as a tool always take the proper precautions so that you can enjoy the benefits without any worries.

I would point out that you should never aim the laser into a mirror and look at the reflection. It is never a good idea to look directly at a laser beam even though the strength is not considered especially dangerous. It wouldn’t be sensible to risk your eyes trying to prove that point.

If you are in business and ever doing a presentation a 5mW green laser pointer would be a real asset, nobody would be able to ignore it.

The only real problem for you when using something like this within a group of people is that so many will want to have a look at it and try it for themselves you will be lucky to get it back again and still have any power left.

It emits a very visible green beam in a dark area, you couldn’t miss it. It is an established fact that the human eye sees green 50 times brighter than the color red

Never be tempted to point this beam at aircraft. Apart from the obvious danger you could bring about by distracting a pilot you can expect to get yourself into big trouble with the authorities.

The 5mW are 100% legal in the US and most other countries but nevertheless this does not mean you should use it indiscriminately, just shining anywhere you think. At peoples windows, cars, people, use it sensibly even in a fun way, and you shouldn’t have any trouble.

The 5mW green laser pointer is the safest one you can use without it having a IR [infra red] filter. It would need a great deal more exposure than 5mW to do you or anyone round you any harm.

The batteries for the 5mW pen are just the small 2AAA batteries which are available just about anywhere. Some of these laser products can have a lifetime of somewhere around 3000 hours, not the batteries of course. Their power life will depend entirely upon how much you use your pointer and on the quality of the pointer that you purchase.

Enjoy conducting your own experiments and learn while you are having fun.
