Shoddy green laser pointer

Everyone would like to get a green laser pointer with at a reasonable price, and thus a large quantity of shoddy laser pointers have flooded into the marketplace. It would be not an easy job to get a green laser at a pleasant price. How to separate genuine lasers from shoddy ones has become a major problem that should be taken into consideration.

I am one of the laser fans and have got some experience on laser selection. First and most important of all should be the understanding of safe use. From the first appearance of 5mW green laser pointer, a large quantity of laser manufacturers and distributors have spring up in the laser pointer market. The fierce competition has forced manufacturers to reduce the cost and improve the productivity, while more and more shoddy lasers have flooded into the market place at the same time. The low cost has made more and more laser pointers are produced with bad quality laser crystals, which has made shoddy laser pointer has become a serious danger to life safety.

Shoddy lasers are commonly produced with bad laser crystals and there is much difference from the usual seen genuine laser pointers. The obvious difference would be that the beams of shoddy laser pointers are not as bright as good quality laser pointers at the same range of output power. The shoddy laser pointers are usually produced without infrared light blocked, which will be quite dangerous but without being noticed by naked human eyes until it’s too late. It must be a brave choice to choose a green laser pointer with IR filter, which is not only in high power and brightness and the most important of all should be that it’s quite safe to use.

The lifetime of green laser pointer is also an important part that should be taken into consideration. Shoddy lasers might burn out within one week time or even shorter, while the genuine green laser pointer might have a long lifetime of about 5000-8000 hours. It must be a good bargain to choose a good quality green laser pointer. Whenever purchasing a green laser pointer, you should have a clear check of the laser beam if there is IR filter or not, and take active measures to protect eyes from damage.
