laser is composed of a special metal alloy

The heat build up will cause the laser diode burned, destroyed by laser.Housing for venomous laser pointer and the Hulk portable laser is composed of a special metal alloy, is a very effective heat dissipation and protection of laser diode.When a 95 MW Viper laser pointer has been in 60 seconds, your hands feel the heat is released from the shell of laser to keep cool.
Pan modification
Design a lot of bad laser only for operation at low power, such as 5 or 10 mw.These lasers have the ability from the battery to the diode increases to a more powerful beam.Modification of the problem is, the laser diode, its shell, lens, crystal, even the on / off switch is not specifically for the higher power and temperature.Most of the changes of laser will burn, not for a few days of things, usually only a few hours.A simple analogy is a 200 W light in the light, is the world's only designed to handle 25 W.Light can work, but it will be long before the frame is distorted, melting, the light was destroyed.
Component quality
The laser design standard inferior to meet specifications.The use of assembly and manufacturing process is fast, cheap.Each component in these inferior laser, diode, crystal, lens assembly, infrared filter (when they have them this is rare), shell, radiator, the circuit board and the battery terminals are very poor quality and a typical life of up to 30 to 50 hours.Green laser we on the other hand, from the world's leading manufacturers and using quality components, meet every international standard.Our laser is to last 5000 hours, we guarantee that reflect this point.
Laser why buy inferior?
The only advantage in green laser pointer to buy the inferior that they sell carrying case / box, attractive sadly even in the case of quality problems, normally closed or mimic knock brand name box, such as "Parker pen" box.These boxes are used to carry a pen, lighter and all other than refined optical and electronic products.Finally, a plastic box can be easily copied or imitated but no alternative to sophisticated laser technology!
