The laser technology of the green green laser pointer was not that mature

The CLASS IIIB, lasers are medium power lasers (5 to 500 mW of power or 10 J / square cm). Examples of the use of Class IIIb laser spectroscopy measuring instrument, laser scanners, stereo photography and entertainment polished light. Look directly at Class IIIb laser is very dangerous, and the scattering of the laser will cause harm to the human eye. Look directly into the Class IIIb laser and a telescope and other equipment to watch the laser is prohibited. Control of the local operation, no matter what time of the laser must wear isolation clothing and goggles. Class IIIb laser device, you must read the Laser Safety Manual. Class IV lasers are high power laser (power: greater than 500 mW or greater than 10 J / square cm). The technology of  green laser pointer  is the newest.
Examples of the use of Class IV laser, surgery, research, cutting, welding machining fiber. Class IIIb laser and the scattering of laser will be the human eye and skin damage. Class IV laser is very dangerous and can lead to fires. Anyone in the Class Iv of laser radiation in the range must wear protective clothing and goggles. Many Class IV laser reflector reflex cause eye burning, so any reflector should be kept away from the Class IV laser. Whenever Do not exposed to the Class IV laser emission range of hands and skin. Hope that these common sense allows everyone to learn how to avoid the Class IV laser. Before the use of Class IV laser equipment, you must read the Laser Safety Manual. The design improvement of  green laser pointer  has been introduced.
Question 12: which the manufacturers of three-dimensional laser scanner is safe laser? The first 3D laser scanner Riegl from his production began to use lasers for eye-safe level (Class I). Optech 2008, also the safety of Class I laser. Question 13: 3D laser scanner in which manufacturers of unsafe laser? What is the level of security? What protection should? Leica, Z & F, Faro, Tempo Class IIIR lasers using insecure to the human eye. In use, the operator mask with eye protection and protective clothing, and can not flow more than the construction site, museum, tourist places, streets, etc.. Less customers would choose the green  green laser pointer  in the past.
To avoid damage after staff. Question 14: When we use a 3D laser scanner to scan the substation, wires and equipment will have terrible discharge phenomenon, what is the problem? Can also use the No? This is because you are using a high energy three-dimensional laser scanner, the resulting strong electrostatic, which is very dangerous. For high-voltage electricity sector, you can only use CLASS I three-dimensional laser scanner Riegl or Optech products can not be used Leica, Trimble, Faro, and Z & F products. Question 15: We often use the total station and 3D laser scanner with the orientation and data stitching work, whether we can use reflection prism as the target of the laser scanner? In the past, the laser technology of the green  green laser pointer was not that mature.
