Regardless of the conditions under which the eyes and skin, will not exceed the MPE value will not exceed the MPE values, even through the optical system is focused. Can guarantee the safety of design, do not need special management. Typical applications such as laser pointer, CD player, CD-ROM devices, geological prospecting equipment and laboratory analysis instruments. Class II: low output visible laser (power 0.4mW-1mW), closed eyes, the reaction time was 0.25 seconds, use this time to calculate the exposure amount can not exceed the MPE values. Usually less than 1mW laser, can cause dizziness can not be thinking, with closed eyes to protect can not be completely safe. The appearance of green laser pointer is very aesthetic.
Do not directly observed within the beam, do not use the Class II laser direct exposure to the eyes of others, to avoid the observed Class II laser afar equipment. Typical applications such as classroom presentations, laser pointer, aiming devices and range finders. Class III: The output of the laser, the beam directly into the eyes, produces injury, and for some security reasons, and further divided into IIIA and IIIB level. IIIA level for visible continuous laser output for the 1-5mW laser beam, the beam energy density should not exceed 25 W / m-m, and, to avoid the Yuanwang equipment observed IIIA laser, so that may increase the risk. A lot in common, such as laser pointer, laser scanner, a typical application of IIIA and Class II level. It can help the customer carry green laser pointer away more conveniently.
III B grade for the 5-500mW continuous wave laser, it is dangerous to directly observed within the beam. But the minimum irradiation distance below 13c m, the maximum exposure time of ten seconds for safety. Typical applications such as IIIB laser spectrometry and entertainment light shows. ClassIV: continuous wave laser of high output (greater than 500mW), higher than the third level, there is a fire hazard, diffuse reflection is dangerous. Typical applications such as surgery, research, cutting, welding, and micromachining processing. Laser gyro on the military use of l Zhang Zhaozhong visitors to respect the Executive: a long time ago, put you as an idol, to see your blog today, I am very pleased to finally have the opportunity to close contact with you to do. green laser pointer is definitely the good assistant and partner for the lecturer, teacher, tour guide, stargazer and explorer and so on.
Program of of view, I also like your article, the deepest impression is the one weapons knowledge on an article about laser gyro, in strict terms, careful argument I admire to vote in the ground. I remember after the end of the war in Iraq, the generation of many short-sighted to attack your network, I also started the debate and those who attack your. Remember when 2004 years now, you said in an interview with CCTV reporter, "China has for decades does not fought" In addition, in the backdrop of today's information age, a single source of information channels will inevitably cause poor health in some cases the judgment on the false impression that these are normal things. So that the product of green laser pointer is green and environmental.
Now, the Central Military Commission, assess the situation and is vigorously military training vigorously engaged in the preparations for military struggle, we resolutely support the leaders of the wise decision, "the country, although large, militant certainly fail; country security, forget the war will be dangerous" I have a small request, you are always in the weekly program and experts to explore the strategic level problem, I would like if possible, can in future programs to talk about the tactical level, such as: People army in the completion of the leaps and bounds from mechanization to information technology, whether the existing command and management system should be adjusted accordingly to adapt to new environmental requirements of war. Salute to the distinguished Executive. at 2007-06-17 14:13:22 Zhang Zhaozhong: Thank you for my long-term concern. green laser is also equipped with the clip and strap.
