Inferior green laser pointer -- what should you expect

In the laser industry, I have met many complaints from the global buyers of counterfeit green laser pointer.In order to help customers understand the inferior laser pointer dangerous and clarify some misunderstanding, we list the following information in inferior laser.
Infrared (IR) lightGreen light (wavelength 532 nm) is the most visible color eye and any green laser you buy should emit green light, only the green light.Our snake laser pointer and the Hulk portable laser for example only gave 532 nm lights.Inferior laser emits green light, although the risk of infrared (IR) light.Infrared cannot be seen by the human eye so that the beam from the laser pointer these inferior is not as bright as it is very dangerous.
You might ask, how can a laser pointer power had an inferior 200 MW but not brighter than 55 mW laser pointer.Here is the trick.We have just said, the laser pointer gave out a lot of infrared ray, can't you see that they are not too bright.Laser power meter but cannot distinguish between the green light and infrared.Laser pointer to an inferior power level of 200 MW of usually will be mostly by infrared.For example, a 200 MW inferior laser pointer is likely a combination of 25 MW green (532 nm) and 175 MW infrared (808 nm).A 55 MW Viper laser pointer 55 MW green light almost no infrared.
All green laser pointer truly and portable laser infrared filter inside that block the infrared light.Laser pointer with the filter removed inferior.Without this filter, the laser pointer is very dangerous, because the infrared rays can damage your eyes, you won't even notice late.
So if you have a high power laser pointer, not very bright, it is most likely to give a lot of dangerous infrared so please use it with extreme care, or even better, to destroy it.
The poor quality of the case shell
Another issue is their poor laser pointer or shell bushing.Their housing is generally made of normal low quality metal or plastic.Module high power solid laser pumped laser generating a lot of heat dissipation, need shell.If the shell is composed of low quality material, heat can not be laser release, will soon establish.
