收到LMD的200mW 532nm
<P>刚收到，还没有加电试验，先上几张图。<br>以后陆续上一些测试结果，但暂时没有写评测或者上效果图的计划。<br>有关购买和价格信息不便于在这里公布，请PM。<br>我购买目的主要是做一些相关试验，前面将做成通用接口可以接不同的镜头，后面将做成通用接口可以接不同的电池（包括18650，要稳压）。<br>警告：激光对人眼有危险，一定要知道你在做什么！</P><P><img src="attachments/dvbbs/2005-10/200510311153857282.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-10/200510311153857282.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-10/2005103111533410853.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-10/2005103111533410853.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-10/2005103111534977711.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-10/2005103111534977711.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-10/2005103112211747722.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-10/2005103112211747722.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br></P>

200mw 功率好大！！难道是米国的产品？先顶了再说~~~~~<br><br><br>

<P>顶啊！不知道电流会多大？</P></DIV>
<P>刚才用两节5号电池简单的测了一下电流，1.1A</P> <P>是用CR123A电池的吗？你用万用表量一下工作电流是多少？</P> 期待详细评测 <P>1.1A是用万用表的10A档测量的。</P>
<P>不会有详尽的评测了，但会有一些实质的、别的地方很少能看到的内容，比如电压-电流曲线、电流-功率曲线、时间-功率曲线。</P> 有效果图吗? <DIV class=quote><B>以下是引用<I>鱼子酱</I>在2005-10-31 20:52:03的发言：</B><BR>有效果图吗?</DIV>

<br>
<P>我的也有类似现象但不厉害。光斑基本是圆的，亮度中心强边缘差。也会变化的的，偶尔花纹变化的突然。但我感觉这是正常的，因为我的100mW的表现也类似，这应该是内部晶体受热变化引起。</P>
