| 5mW laser pointers recommendation |

Laser pointers are fun, that’s why they are so popular around the world. Young people love green laser pointers especially because green laser pointers have a higher visibility than red or blue ones. And they love laser pointers with high mW, the higher the better. However, laser pointers with high mW are dangerous products to play with.
The higher the mW is, the further a laser pointer can be seen. A 200mW laser pointer can be seen across a long distance even in the day light, especially a green laser(http://www.pickegg.com/wholesale/green-laser/). But it would cause permanent damage to human eyes if they are pointed directly. On the contrary, a 5mW laser pointer is much safer which can be used as a teaching tool or used to play with your pets, although you should not point it into human eyes either.
Here I want to recommend a purple laser pointer with 5mW and 405nM. It’s a slim pen shaped laser pointer which is quite portable to carry around. It is made of high quality brass and powered by two inexpensive AAA batteries. It is suitable for presentation use, for example, meetings, class etc. it’s not suitable for those who want fun, but it is right for those who use it for serious usage.
Some people may be not so excited about the above laser pointer because it’s not green laser. well, as I said before, green lasers do have a better visibility compared with the others. So, here I want to recommend another 5mW green laser pointer. This is also a pen shaped laser pointer as most of the lasers do. This one shares most features with the above one, only this one is more attractive. And this one only needs 17.99 bucks with free shipping around the world. |
