Green laser pens, the latest craze sweeping around the world. You have probably never heard of them before? Surely every one knows about RED laser pens? Shining it about and seeing how far it will go, reaching the top of building and over fields.

Well now Green Laser pens are now available. They used to be out of the reach of the general public due to the high cost and bulky weight. But due to advances in technology and developments, Green laser pens have come down in price, and size to be easily accessible to all.


There are a few things you need to know about Green laser pens

Firstly, they come in different power ratings. The power rating is in mW which stands for milliWatts. The minimum is 1mW. Most start with 5mW though. They can go all the way upto 500mW although 100mW is more the norm as after that the Price is just spot on. The more powerful the unit is, the further the green laser beam can be projected. A 5mW can be seen for 2miles!!!

Why do people buy green laer pens? Well, i first bought one when i came across them on the internet. I had never seen one before. I didnt know they existed. I only thought red ones were available. Well i got one anyway and i got to say i was impressed. The beam of the laser pen was visible, which isnt the case for a red one, except when it is shined into fog or smoke. The Green beam will be visible where ever you point it. Also i was impressed at how bright it was, it was alot more powerful than a red one. When i first used it, i shined it to the ceiling and it lit up the room in a green glow. Then i used it outside and was shining it on these flats approx 1.5-2 miles away. I guess i got carried away. Its very fun to use no matter how old you are, referencing to my 46yr old neighbour who was shining it in people's bedroom windows acting like a 10year old.  

Green laser pointers have been around for a few years but what are they? We have all seen the red laser pointer \ pen but green is completely different. The most common type are DPSS, ( diode pumped solid state).  They are also 50 times brighter than red. With green laser's, you can see the beam as well as the very bright dot. Green laser pointers are the preferred laser pointer because green is the most visible laser pointer color. The reason why green is more visible is the human eye is most sensitive to green light. Class 3B lasers may have an output power of up to 500 mW (half a watt) and a laser with an output power of around 100mW and above is capable of melting black plastic (Bin bags), making holes in bin liners and popping black coloured balloons or balloons marked with a black marker pen. To give you an idea of what to expect, if you were to enter a room that is pitch black and used the laser on the ceiling, you would be able to see everything in the room. It lights the room up in a green aura. The beam would also be very visible looking like a green beam stretching out. When used outside, the beam seems to reach the stars, it would reach any building you see in the distance. The power output of laser's are measured in mW (milliWatts) and can range from 5mW to around 500mW. of course the more power you have, the easier they will burn and the brighter they are.


They are super bright!You must be careful. If you shine one say in your room with the curtains and lights turned off. You will see the actual beam. You do not need any cigarette smoke or fog enhancer. The beam is visible. Obviously the more powerful the green laser pen the more visible the beam is. Safety is paramount!

Green lasers are superior to red ones, here are some advances

Green laser pens are 50 times more powerful than red ones. This is just in general. This is because the eye is more sensitive to green light than red light. A GREEN 1mW vs a RED 1mW, a green laser pen will always win. If you look at a light spectrum chart you will see. so a 5mW green laser pen is 50x more brighter than a 1mW red laser pen and over 250 times more powerful!



  • EXTREME HIGH POWER, YOU GET GET THEM FROM 5mW TO 50mW, 100mW UPTO 500mW+ Output.
  • 50x BRIGHTER THAN STANDARD RED LASER PENS.
  • INDUSTRIAL CLASS IIIB GREEN LASER.

  • DESIGNED TO OFFER YEARS OF RELIABLE USE.
  • BURNS BLACK PLASTIC AND LIGHTS MATCHES! (HIGHER POWERED MODELS).
  • CLASS LEADING HIGH POWERED PERFORMANCE.
  • SUPERB OPTICAL PERFORMANCE
  • BATTERIES INCLUDED (READY FOR IMMEDIATE USE)
  • BRIGHT GREEN BEAM PROJECTS FOR MILES, FROM 2-40MILES DEPENDING ON POWER MODEL.
  • USES EASILY AVAILABLE AAA BATTERIES.


Picture Difference

As you can see below, there is a comparison between a Red and a Green Laser pen. The red one is small and has three button batteries. This gives it limited power and time for use. The green is larger due to being relatively new on the market, in time they will shrink in size. It take 2xAAA batteries. This gives it the power and time consumption for it to be effective.



There are many uses for the Green laser pen as well. There are medical uses, Army combat uses-elite soldier use them for training and on missions, astrology-pointing at the stars, presentations-they are clearly more visible and you can use them further away, On site for construction uses. Thens theres the Good old Fashioned shining it about in the dark seeing what the further you can hit it with!

So Many Uses:
Astronomers
Teachers
Students
Bird Watchers
Presentations                                            
Tour Guides
Construction Workers
Scientific
Military
Security applications
Use to point out distant points of inerest
Just for fun, point it at what you want.

Common laser power available: 10mW, 20mW 30mW, 50mW 80mW 100mW 120mW 150mW 200mW 250mW 300mW 350mW 500mW.

I hope this has been useful. If you have any questions/comments or useful suggestions on how to make this guide better just let me know and i will take it seriously! Thanks.

Im getting some great feedback on my Green lasers Pens i have on sale so take a look here - Genuine Green Lasers

WARNING

WARNING- There are many fakes green lasers on ebay. These are the ones that are advertised as 100mW - 240mW. Some 100mW pens are legit though. They are sold at such a low price that even manufacturers cannot make them at that price. How do they do this? They sell a 5mW and claim it is 240mW!!!. Do not fall for it. Look at the feedback and you will see they are about 97-98% with plenty of negatives. You have been warned!!

WARNING- Do not fall for the auctions that claim the diode of the laser pen is made by Seimens etc this is utter bull. All designed just to make you think the laser pointer is made by a reputable firm. Also they claim the diode is 1-2watt diodes, again just fabrications of the truth. If they put in claims such as shock resistant and thermal cooling then you know they are clearly lying. These are not built into laser pens, they are only built into the professional ones that cost upwards of £400+. Also be weary of claims that the laser pen is tested by expensive equipment such as a power meter, they usually put ones on that cost £1000+ just to test a laser pen that is worth £30.

WARNING- If you plan to buy a pen on ebay but are not sure if its a legit one, or if the power mW is as thy say it is, feel free to send me a message through ebay and i will check it out for you. I have 15+ years dealing with laser pens and i can tell most of the seller on ebay if they are selling fakes. I am not charging anything or asking for anything in return just to let you know. I am just tired of people getting conned. Please include the name of the ebay seller you plan to buy off/are looking at when you send me a message so i know who to look at. (As of the date of 1th OCT 2008, i have helped 173 people) Regards. I sell genuine laser so be sure to check mine first.

Infra red filter Warning!
Lasers give out  a lot of infrared light which you can't see. But they are very dangerous to your eyes.  Laser power meters however cannot distinguish between green light and infrared light. Although they measure both. Some inferior laser pointer will normally be made up of mostly infrared light. For example a 100mW inferior laser pointer is likely to have a combination 20mW green (532nm) and 80mW infrared (808nm). All genuine green laser pointers and portable lasers have infrared filters inside them that blocks infrared light. This is vital to protect your eyes.  Some laser pointers have had this filter removed or have been manufactured without the filter. Without this filter, these laser pointers are very dangerous because the infrared light can damage your eyes. All the laser pointers we sell contain the correct IR filter.

How can you be sure the laser you are buying has the correct power output?
Some unscrupulous sellers will offer a high powered laser that is less than half the real power or may not even know the correct power as most sellers do not have access to a proper calibrated power meter. We test each and every laser pointer before it is shipped to you with our optical power meter. The enables us to accurately measure the precise output power of every laser pointer we supply and guarantee the power before it is shipped! We have been selling green laser from the very beginning with our 1mW over 5 years ago. Experience is everything. Get your green laser here- Green Laser Link
