<P>波长:8-12微米</P>
<P>焦距:50-200mm</P>
<P> 目前的问题是中心波长在中间焦距位置的球差比较大(pic1),对它进行优化结果边缘波长在长短焦位置的像差增大了(pic2),想问问大家应该侧重于中心波长降低边缘波长的权重还是都要综合考虑</P><img src="data/attachment/forum/dvbbs/2004-9/20049291550342.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(\'data/attachment/forum/dvbbs/2004-9/20049291550342.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
