这个东西比较巧妙,单纯镀膜很难实现

<P>加一道光刻就可以了。</P> 这个东西在光学引擎投影显示中用得着的 <P>偏振分光棱镜拼接在一起。<img src="http://bbs.oecr.com/Skins/default/topicface/face12.gif"></P><P>半波层是不是用来调节位相的:</P> 这种产品我们正在做,工艺较复杂。不过相对于X-CUBE,它是很简单的。 PLC嘛,有什么了不起的,比起X-CUBE简单多了,它的难点就是外观,特性还是很好镀的. X-CUBE,有兴趣,说来听听,是那方面难呢? 我公司做过 现在没做了? 交合斜面上100%镀上膜,二个平行平面也得100%镀上减反膜(包括半波片),胶合前的零件大小为3~5mm。镀膜的曲线要求很普通,可是做在如此精细的零件上,不是件容易的事。
