When red laser module is equipped with qualified line emitting lens, such as glass cylindrical lens or separate crystal lens, it forms into an industrial stabilized red laser line pointer. According to the configuration of wide laser lens degree of 10 to 110 degree, this laser line module generates different laser beam fan angle, forming into various line length and line thickness in distance. It is also accepting customized manufacturing, which can fulfill the most precise line alignment and measurement in all precise device manufacturing works efficiently.
5mW green laser pointer belongs to Class IIIa laser with 532nm wavelength, uses two AAA batteries. This type of green laser projects 532nm green laser beam with high brightness, so it is extremely dangerous to eyes, especially high powered lasers. In many countries and regions, only allow 5mW green laser pointer.
Early laser pointer only uses 633nm helium-neon (HeNe) gas laser, typically for generating power of not exceeding 1mW laser beam. The cheapest laser pointer uses near 670nm/650nm dark red laser diode. Slightly more expensive laser pointer uses 635nm red laser diode, with near orange red color laser light. 635nm wavelength is much more easily recognized by human eyes. At the same time, there are other colors of laser pointers, the most common is the wavelength of 532nm green laser pointer.
405nm blue violet laser pointer also gets the name of violet laser pointer. The first clarify should be that blue violet laser is not an argon laser, majority people have been misled blue violet laser is the same as a decade ago argon laser. However, in fact, blue violet laser and argon laser are completely different laser tech.
There are wide choices of blue lasers for laser amateurs and researchers. Besides formal application for entertainment and simple presentation, blue laser pointer is even more workable for high tech working fields. For instance, 450nm blue laser pointer can be used to make presentation in high definition blue ray players, laser show, environmental monitoring, electronic equipment, medical diagnostics, laser activated paint etc.
When laser pointer is in formal work, it always requires certain operating environment. Generally its acceptable operating temperature is range from 10 degree to 40 degree Celsius. Some special laser pointers might be workable under operation temperature with range level of 0-40 degree Celsius, or even lower operating temperature.
