More customers order more infrared green laser pointer

The infrared  green laser pointer  is relatively cheaper. Grade Ⅰ: This laser will not pose any known degree of injury. Class IA: This is a special level, means "not suitable for direct viewing with the eyes" of the laser, such as supermarkets use of laser scanner. The maximum limit for this level of laser power of 0.4 mW. Class II: refers to the low-power visible lasers, the transmit power level higher than I, but the radiated power does not exceed 1 mW. Defense of human response to strong light and automatically protect humans from harm. Class IIIA: refers to the low-power laser (continuous wave :1-5 mW), only within the beam, as the case would constitute a hazard. Most of the pen-shaped laser pointer belong to the class. Class IIIB: refers to the general power of lasers. Class IV: refers to high-power lasers (cw: 500 mW, pulse: 10 J/cm2 or the diffuse reflection limit), under any circumstances, whether direct or indirect observation is at risk, and may cause a fire or burn the skin. Class IV laser device must accept strict control. The infrared  200mw laser pointer will be used in many locations.
Present in the laser industry, laser safety rating four levels: Class I: low output laser (power less than 0.4mW), regardless of the conditions under which the eyes and skin, will not exceed the MPE value, even after focusing through the optical system will not exceed MPE values. Can guarantee the safety of the design without special management. Typical applications such as laser pointer, CD player, CD-ROM devices, geological prospecting equipment and laboratory analytical instruments. Class II: low output of the visible laser (power 0.4mW-1mW), who closed the eyes of the reaction time of 0.25 seconds, use this time to calculate the exposure value can not exceed the MPE. Usually less than 1mW laser, will lead to dizziness can not think, with closed eyes to protect, can not say completely safe, do not observe directly in the beam, do not use ClassII direct exposure to laser eyes of others, to avoid the observation of Class II equipment with afar the laser. Typical applications include classroom presentation, laser pointer, aiming devices and range finders, etc. Class III: the output laser beam directly into the eye if would have hurt, for some security reasons, further divided into IIIA and IIIB level. The infrared  green laser pointer  sells well in the market.
Class IIIA laser for the visible light of continuous output of 1-5mW laser beam, the beam energy density of no more than 25W/m-m, avoid using afar observed IIIA laser devices, this may increase the risk. Typical applications IIIA and Class II level have a lot in common, such as laser pointer, laser scanners. III B class of 5-500mW of continuous laser beam to observe directly in danger. But minimum irradiation distance of 13cm, the maximum exposure time of ten seconds the following for safety. IIIB typical applications such as laser spectroscopy and entertainment lighting show. ClassIV: high-output continuous-wave (greater than 500mW), higher than the third level, there is a fire hazard, diffuse reflection also at risk. Typical applications such as surgery, research, cutting, welding and micro-mechanical processing. Although the laser safety levels have been defined, but for the human body, especially the human eye, the damage is different at different wavelengths, and therefore, although two or three of the laser, the same should be noted. More customers order more infrared  green laser pointer .
Different wavelengths of laser eye injury site, the wavelength partition wavelength range (nm) primary site of injury, 180-400 UV laser cornea, lens, visible laser 400-700 retina, choroid, near-infrared laser 700-1400 retina, choroid, lens, in Far-infrared laser 1400-106 cornea, the laser operating environment in the long-term workers in the eyes by long-term effects. In operation and use of lasers, even if not directly by the laser irradiation, resulting in injury accidents. However, the anti-out laser rays through walls or other objects produced by micro-reflections, long-term work in this environment of people, a high incidence of cataracts. Prolonged exposure to green laser light, especially when the laser pointer over 5 mW of power, just a few seconds may cause functional vision of the human eye damage. The company needs to purchase more infrared  green laser pointer .
Before the eyes of my colleagues once smashed by the laser. The results gave the company lost a little money. The key is self-inflicted injury, loss is difficult to estimate. Especially for industrial processing lasers are now engaged in those who are even more so. The safety level of laser processing are generally four (most dangerous), and now there are many applications of laser is not visible in the scope, the more light that is not visible, the more dangerous. Can see the laser, most people know not to look directly at, but not visible only rule of thumb to determine where there is no light, should not be read. The infrared  green laser pointer  is not the main product of this company this year.
