[求助]有没有激光产品安全分类标准

各位高手，我想知道有没有激光产品安全分类标准啊，有的是3A类激光产品，有2类激光产品，怎么分类的？请教各位！谢谢！

是按照激光的功率分类的，0.4mw-1mw是2类，1mw到5mw是3A类。

<ul type="disc"><li class="MsoNormal">Class I lasers - Lasers that are not hazardous for continuous
viewing or are designed in such a way that prevent human access to laser
radiation. These consist of low power lasers or higher power embedded
lasers (i.e., laser printers). <op></op></li><li class="MsoNormal">Class II visible lasers (400 to 700 nm) - Lasers emitting visible light which
because of normal human aversion responses, do not normally present a
hazard, but would if viewed directly for extended periods of time. (like
many conventional light sources). <op></op></li><li class="MsoNormal">Class IIa visible lasers (400 to 700 nm) - Lasers emitting visible light not
intended for viewing, and under normal operating conditions would not
produce a injury to the eye if viewed directly for less than 1,000 seconds
(i.e. bar code scanners). <op></op></li><li class="MsoNormal">Class IIIa lasers - Lasers that normally would not cause injury to
the eye if viewed momentarily but would present a hazard if viewed using
collecting optics (fibre optics loupe or telescope). <op></op></li><li class="MsoNormal">Class IIIb lasers - Lasers that present an eye and skin hazard if
viewed directly. This includes both intrabeam viewing and specular
reflections. Class IIIb lasers do not produce a hazardous diffuse
reflection except when viewed at close proximity. <op></op></li><li class="MsoNormal">Class IV lasers - Lasers that present an eye hazard from direct,
specular and diffuse reflections. In addition such lasers may be fire
hazards and produce skin burns. <op></op></li></ul>

Here is another description, paraphrased from the CORD
course: "Intro to Lasers". (<a href="http://www.cord.org/">Cord
Communications</a>. Lasers.) It relates the laser classifications to
common laser types and power levels: <op></op>
<ul type="disc"><li class="MsoNormal" style="line-height: 150%;">Class I - EXEMPT LASERS, considered 'safe' for intrabeam
viewing. Visible beam. <op></op></li></ul>
Maximum power less
than 0.4 uW. This will not cause damage even where the entire beam enters the
eye and it is being stared at continuously. <op></op>
<ul type="disc"><li class="MsoNormal" style="line-height: 150%;">Class II - LOW-POWERED VISIBLE (CW) OR HIGH PRF LASERS,
won't damage your eye if viewed momentarily. Visible beam. <op></op></li></ul>
Maximum power less
than 1 mW for HeNe laser. <op></op>
<ul type="disc"><li class="MsoNormal" style="line-height: 150%;">Class IIIa - MEDIUM POWER LASERS, focused beam can injure
the eye. <op></op></li></ul>
HeNe laser power
1.0 to 5.0 mW. <op></op>
<ul type="disc"><li class="MsoNormal" style="line-height: 150%;">Class IIIb - MEDIUM POWER LASERS, diffuse reflection is not
hazardous, doesn't present a fire hazard. <op></op></li></ul>
Visible Argon
laser power 5.0 mW to 500 mW. <op></op>
<ul type="disc"><li class="MsoNormal" style="line-height: 150%;">Class IV - HIGH POWER LASERS, diffuse reflection is
hazardous and/or a fire hazard. <op></op></li></ul>
