大家来看看超级聚光的树脂透镜,有3W光斑图看,光斑奇特!呵呵

<P>能把透镜照个图,看看样子吗?为什么会超级好,能射100米 普通透镜只能射30米?是聚光角度小吗? </P>
<P>那里有买的?15mm好!就是想找小点的.</P> 是不是只有LED用透镜才有效果？ <P>上个图看。</P> 100M别的透镜也能做到啊，你要描述100M后的效果，如果只能看到一点点影子，别的透镜也能做到 <P>大家有什么问题 就加QQ116790367 漫漫聊 在这里聊太慢</P> 咱没有也不会QQ啊. <P>再上几个光斑图 都是用透镜的 从上至下分别是25度 15度 10度</P>

<P>老沈 你好 我白天都在上班 晚上才上网 想聊的话 发一卖耳给我:lmyc402@suho.com 或者QQ116790367 实在是很急着要和小弟联系可以短信息联系13701728389,万不得意才发消息啊 ,呵呵 还是一卖耳吧 </P>

这个透镜直径是15mm,最厚处约多少?距LED约有多远? 咱自己用透明片做一个.
[此贴子已经被作者于2005-10-20 19:42:46编辑过]
老沈好强! 厚度最大17mm 老沈,做 ....做一个???

<P>明天出个尺寸图给大家看</P>
[此贴子已经被作者于2005-10-20 21:14:44编辑过]
<P>17+25+开关长度+LED长度=<=60MM手电</P>
<P></P>
<P></P> <P>直径15的能射100M,真的吗,不怎么相信啊</P> <P>关键是发射角度，如果能搞到小于1度的杯子或透镜，射200m也不稀奇，那个maxabeam的特点就是反光杯的发射角度小。</P>
<P>不过发射角度太小也不好，象激光一样，结果照明面积小，反而不好用。再说LED手电光通量普遍较小，光束的穿透力又不强，就算照到100m外估计也看不清楚了。</P>
<P>要玩远射程还是上探照灯吧。</P>

咱一个月前就备好了透明片了,最厚的才10mm.老想着磨一把刀,夹在台钻上出毛坯,再用磨料抛光(也用台钻).虽然没试过,应该行得通.手电透镜比放大镜要求应该低多了. 就是曲线要找本书出来看看..... 问多星好: 咱还没有私聊的习惯,大多在帖上说.隅而用短信. 老沈，你好人家太厉害了，佩服佩服 <P>我现在有这样的要求,使用1W或3W的LS,光杯直径在30VMM之内,150M处我要看到事物;不知能否实现</P>
