<P>前面有个相关的设计,不过畸变控制的一般,我设计的也是4mm,F数2.8,FOV也是80度,畸变控制的还行(有图为证),MTF就没那么好了,50lp/mm0.5,一般用用也可以了,呵呵。</P>
<P>如果需要,请加我qq:45711978,注明OECR</P><img src="data/attachment/forum/dvbbs/2005-1/20051131613938.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/2005-1/20051131613938.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
