<P>听杭州绿意的销售大哥说，这支5MW的笔，出厂功率检测达到了7。</P>
<P>反正不管功率如何，效果我非常满意。</P>
<P>对于一支低价位，小功率的激光笔，能做到这样，我已经非常满足了。</P>
<P>晚上，象对面的学校照去，一根直直细细的光柱直穿过操场。</P>
<P>距离基本可以照到800米的建筑物上，还能看见绿点，对于光点的扩散也做的相当不错了。</P>
<P>近距离光点，无杂光，说明人工晶体的纯净度可以。</P>
<P>天气好的话，晚上可以用来指星星。自己看很明显，但边上人离开几米远就看不见光柱了。</P>
<P>估计要让几米外的人同样可以看到指星的路线，需要15以上的功率。</P>
<P>在测试中发现，晚上如果风很大，光柱效果不明显。天气晴朗的晚上，效果更佳。</P>
<P>有时候不需要等到夜间才能看见光柱，黄昏，傍晚的时候就能很明显的看见光柱了。</P>
<P>其实最这支笔最另我感动的是，杭州绿意的销售大哥，得知我的笔质量有问题的时候，主动愿意帮我换产品，直到我满意为止。（后来证实是我用的电池质量不过关）</P>
<P>而且他的发货速度超快，当天付款，隔天就到。“性欲”（信誉）真的不错啊。哈哈</P>
<P>上面的是我真心感谢的话，其次也是觉得产品不错，帮他推销一下，含有广告成分：）</P>
<P>总之，资金有限，但想骚一把的朋友，不要错过这款小功率的绿光了，哈哈。</P>
<P>简短评测到此结束。发现新问题，再和大家讨论。</P>
<P>我会把公司相机带回去，晚上拍广角给大家看。哈哈</P>

<P>顶了再看</P>

<P>呵呵，好象大家对我的评测不敢兴趣啊</P>

<P>刚才量了下，10米，光点5毫米</P>
<P>我就觉得他的光点很纯，一点都没杂质</P>
<P>我的武士红光，近距离都有杂质</P>

<P>最后一张ISO好象是100的</P>

<P>我还发现一个问题，这东西怎么越用越亮。不是说持续时间，而是天数</P>
<P>第一天，很暗（我用的烂电池）</P>
<P>第二天，好电池，亮了很多，很爽</P>
<P>第三天，同样的电池，比第二天还亮。</P>
<P>这是什么原因？</P>

lymex

<P>有关激光笔的发散，厂家都是给出10m距离光点&lt;15mm，实际12mm左右，如果是5mm，那么可能测量不准（比如距离不够）。</P>
<P>越用越亮很可能是感觉问题，最好找个客观标准，比如用老式的绿色不透明LED作为光电二极管，用数字表的200.0微安档测一下光电流。</P>

<P>可是我确实量下来是5MM啊</P>
<P>用尺量的，</P>
<P>距离也是10M</P>

<P>那我知道了。我说的发散到12mm的是指光出口直径1.5mm那种的，发散比较大。你这个看照片好像出口直径比较大是吧？因此发散比较小。我们前几天做试验让出口直径大到5cm，结果传输了1.4公里后，发散成不到8cm。</P>
