What is a violet laser module?
Violet laser module emits laser light within violet spectrum regions between 390nm and 419nm, which gets the most commercially common available wavelength of 405nm violet light. It gets the shortest wavelength than formally available blue, green, red lasers among visible optical spectrums. It is a short enough wavelength to caused fluorescence in chemical experiment.
Varieties of Laser Pointers
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 Lasers
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.
