Green Laser Pointers
For those who like to keep up with the most current trends, but want something functional as well, green laser pointers may be exactly what you need. Unlike the standard red pointers found at gas stations, toy stores and even grocery stores, green laser pointers are far less common and have the visual appeal that has long since died for the red pointers. However, there are a few things that you should keep in mind when you are selecting which green laser pointers are right for you.
Because of their relative young age, green laser pointers are more expensive than red ones. The technology is yet to be so common that the pieces can be easily gotten and assembled. Because of this, you can expect to pay notably higher for them, and you may have to spend longer time looking for your new pointer than you would if you would be searching for an equivalent red laser pointer. If you keep this in mind, however, you will be able to find the green laser pointers that are perfect for your needs.
The first step in selecting green laser pointers is to determine the strength of the pointer you need. You can acquire green laser pointers with a strength of 5mW or less, which is legal across the vast majority of the planet. You can order laser pointers of this nature from any local or online store without any worries of import problems. If you want stronger green laser pointers for use in sky viewing and astronomy, you will need to take care in where you purchase and keep your pointer. Many areas have laws relating to the ownership of green laser pointers that exceed the limit of 5mW. As you need a mW value of 100 in order for the pointer to be good for use as an astronomy pointer, these pointers are often illegal. If you purchase green laser pointers of 5mW or higher, the manufacturer transfers all liabilities to the consumer. Because of this, you should be aware of what you are purchasing before you do so.
When using green laser pointers of any strength, there are a few things that you should keep in mind. First, you should remember that these items should not be treated as toys. If pointed into the eyes, irreversible damage can be done to the retina, which can cause minor to severe loss of vision. Once burned, it is impossible to correct the damage done, as corrective laser surgery cannot overwrite the damage done by another laser. In addition to this, green laser pointers should never be pointed at any sort of vehicle, as it can cause accidents or bring harm to the operators and passengers.
