Yes most are because they can blind people and can crash planes and helicopters. I think that 1mW and less is legal but I might be wrong
In most jurisdictions in most countries including the United States, pointing a laser pen at an aircraft is illegal. It is possible at night to cause a visual disruption to a pilot.
Laser pointers and laser pens are basically the same thing. A laser pen is a laser pointer with a pen attached.
Lasers differ in price between manufactures and quality. i have found a 100 mw laser for $16.00. But as a buyer you have to be careful, ordering any laser over 5mw to the U.S is illegal. I do not know how strictly it is enforced. Correction to your reply: Lasers over 5mw are illegal to IMPORT to the USA. 100% legal to purchase in the US
Some laser pens are not dangerous indoors. A laser pen with five mW will not harm someone and is visible enough to see. But other pens which have one hundred mW are very dangerous and are a hazard.
No they are not. The difference is the light. Laser pens will have the red shining light while the infrared pens won't have any visible light. The only way you will be able to tell if it's working (the infrared pen) is you have to test it against either a wiimote or camera lens for more information visit http://infraredpens.com/
They are illegal in some countries, but not all of them. Idon't know if they're illegal in the US, but probably not.
No
Many luxurious pens, such as fountain pens, have engravings on their outer shells. How are they made? What are the manufacturing methods? Hand-engraving, laser engraving, or CNC machining?
In schools they are generally illegal for a student to possess.
There are many stockists of lasers in the UK. A good source is ebay if you are looking for a laser pointer. Another is laser pointers. Amazon is also a good source of different laser pens and pointers.
don't its illegal unless you have a licence
Yes they are illegal. If you are caught with one then you will be fined £2000.
