Description

http://www.lasereshop.com/blue-laserpointer/p-1.html
Apparently, it is mainly the ‘divergence’ of the laser beam to determine the price of a laser pointer: the extent to which the beam spreads once it leaves the laser. The divergence is as low as possible for astronomy purposes. Unfortunately not always that specification long to find.To illustrate: the laser I ordered now has a divergence of 1,3mrad and has a beam diameter chassis at the opening of 1.2mm. Regarding divergence is not ideal, but hopefully enough to use what I intend. There is a class of Ultra Powerful Laser Pointer , IIIa, which by law must be less than 5mW (of measured optical output, not electrical input). This class is legal to sell in the United States, and legal to operate outside in the United States (local or state exceptions may exist) provided you don’t do anything stupid. http://www.lasereshop.com/laser-accessories/p-185.htmlShining the laser at aircraft in flight, or moving cars, or other equally moronic acts can easily land you in prison for an extended time (and rightly so). Apparently a man who wanted to see if he could hit airplanes as they were landing was in fact successful. Thankfully, none of the pilots crashed, but the man was reported to have received a seven year prison sentence.The next higher class, IIIb ranges from 5 to 500 mW. You can also legally purchase this class of laser in the United States. But there are restrictions on it’s use, because these lasers are capable of permanently damaging vision. You can’t use it in an environment where the beam could escape to the outside. To be explicit here, this means you can’t legally use them outside. Now you may want to adopt a “no blood, no foul” attitude, and that’s fine for you. But just know that if you ever make a mistake, or run into a narrow-minded individual, you don’t have a legal leg to stand on – prepare for a good screwing. Furthermore, based on my own
