请教定光轴规格问题，急请前辈指导。

<P>请教一下各位前辈、师兄，请问怎样定光轴倾斜公差的规格，要考量哪些因素，我只知道在我们这个行业应该在30'左右，我这个是光学头（CD）的光路系统。谢谢指教。</P><img src="data/attachment/forum/dvbbs/2005-6/200562011241198927.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/2005-6/200562011241198927.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR>

按加工装配的公差就可以了
