此膜系是应用于光驱中的光学零件,有专门测试相位差的仪器,可以批量测试.楼上的设计光学要求是达到了,但是在工艺上较难实现,主要是部分TiO2层太薄了,其次是镀银可能不是很好镀. </blockquote></div><br /> 全介质膜也不好做,满足前3项就需要21层了.Ag蒸发还是好镀的.<br /> <strong>δR=6±10度(入射角度45,波长655nm),δR=-4±10度(入射角度45,波长790nm),波面差在(1/8)λ以下</strong><br /> 请问楼上的兄弟,是不是180度就是0度,可以这么理解吗?655nm落在176-196度,790nm落在166-186度就可以了?波面差怎么理解?<br /> 光驱镀膜多用sputter吧,日立环球和新科有做,我想没有这样的技术要求吧.</div> <div class="postmsg">在位相的角度看,180度与0度是不一样的,光波的位相在0度与180度时,其偏振方向差90度.这个差别在光驱光学系统里是很重要的,否则就完全不能用.δR=6±10度与δR=-4±10度的要求是光驱识别CD和DVD牒片的一个必要条件.<br /> 波面差是对光学零件加工精度和光学设计要求的参数,就是引起光干涉的光程差要求.(1/8)λ是一个干涉极值条件,极易引起干涉.通过镀膜或零件加工可调节波面差.</div> <div class="postmsg"><div class="quote"><blockquote>原帖由 <i>nittohai</i> 于 2007-10-4 10:59 发表 <a
