Typical Laser Diodes
The most common laser diodes of visible wavelength have 635nm, 650nm for red laser, and 405nm, 445nm for blue laser. As the green laser diode, it's still in developing period. Most green laser still use the DPSS(Diode Pumped Solid State) way to create the 532nm laser by 808nm laser diode......more |

Laser Module, laser pointer Specifications No.1
Wavelength: Usually, closer to 540nm is better since visibility is a strong function of wavelength. However, the variability can be significant - a laser pointer at 640 nm could indeed be closer to 650 nm and there's almost a 2:1 ratio of relative brightness. Or 450 nm blue laser could be much brighter than 405 nm......more |

Diode Laser Safety
As the CE of Europe safety rule requests class 1 <0.39mW, class 2 <1mW of collimated laser for the consumer products would emit the laser to the eyes. And the FDA of USA allow the class 3A <5mW for the consumer products. As the detail safety rules would be different for different applications and area, you also can contact EGISMOS to inquire......more |

Laser Module, laser pointer Specifications No.2
Distance/range: Laser light doesn't travel a specific distance and stop, or suddenly become too dim to be seen. It's only possible value would be in comparing various models, they probably just associate a particular value with the output power, wavelength, or the the laser spot size of the operating distance......more |
