We have come across many complaints online from buyers all over the world about shoddy green lasers pointers. In order to help customers understand the dangers of shoddy laser pointers and clear up some misunderstandings, we've listed below information on shoddy laser pointers.
The color of a laser beam is determined by the wavelength of the light given out by the laser diode in the laser pointer. Our laser pointers ONLY give out green light. Green light is the most visible color to the human eye. This makes the beam from our laser pointers very bright with a spectacular vivid green color. Shoddy green laser pointers on the other hand do not just give out green light, they also give out infrared light. Infrared light cannot be seen by the human eye so the beam from these shoddy laser pointers is not as bright as it should be and is also very dangerous.
You may be asking why a shoddy laser pointer can have a power of 200mW but be less bright than a 50mW dragonlaser. Here is the trick. As we just said, these laser pointers give out a lot of infrared light which you can't see making them less bright. Laser power meters however cannot distinguish between green light and infrared light. The 200mW power level of a shoddy laser pointer will normally be made up of mostly infrared light. For example a combination 25mW green (532nm) and 175mW infrared (808nm). A 50mW dragonlaser will be 50mW green with virtually no infrared.
A genuine green laser pointer has an infrared filter inside that blocks infrared light. Shoddy laser pointers have had this filter removed. Without this filter, these laser pointers are very dangerous. You can damage your eyes and not even be aware of it until to late.
So if you have a high powered laser pointer that is not bright, please destroy it immediately because it is dangerous to your health.
Another problem with shoddy laser pointers is their shell. Their shell is commonly made out of normal metal or even plastic. A high powered DPSS laser module generates a lot of heat. If shell is made out of poor quality material, the heat from the laser can not be released and will build up inside very quickly. This will cause the laser to burn out and be destroyed. The shell for dragonlasers is made from a special metal alloy. When a 95mW Dragon GLP has been working for 60 seconds, your hand can feel the heat been released from the shell as the laser is kept cool.
Some customers are attracted to shoddy lasers because they use high powered rechargeable batteries. The secret of laser technology depends on many things but one of them IS NOT batteries. A shoddy laser pointer with high powered batteries still gives out a weak green beam.
A shoddy laser pointer is completely different from a genuine dragonlasers GLP, the Laser diode, crystal, lens...every component is different. Shoddy green laser pointers can usually only work for 30 to 50 hours before burning out and becoming useless.
The only advantage in buying a shoddy green laser pointer is that they are sold with beautiful carrying case. The problem with these boxes is that they are imitation "Parker Pen" boxes that are designed for pens not laser pointers.
A plastic box can be easily imitated, cutting edge lasers technology cannot be imitated!
