<b>讨论：国内冷加工能否满足DWDM 基片的要求？:</b><div class="postmsg">如光洁度、平行度等。</div> <div class="postmsg">可以达到的,但要有过硬的冷加工经验,经典的超光滑表面加工就可以!</div> <div class="postmsg">多谢两位！<br /> 不过经过加工后的基片如何保存？能保存存多长时间？<br /> 需要加工到什么程度才算超光滑表面<br /> </div> <div class="postmsg">如果只是将镀膜后的基片进行再加工，那么应该问题不大，但是如果说靠冷加工去重新做新的基片，国内目前的水平是不可能的。</div> <div class="postmsg">shanyu:<br /> 你的不可能是错误的，国内有经验的冷加工师傅是可以做到的，经典的超光滑表面加工！粗糙度到0.5nm，不过不是100%的成功，有时会有点划痕什么的，但大部分的产品完全满足DWDM的要求！</div> <div class="postmsg">看来IC5那里有这样的高手了，<br /> 用什么检测能不能用呢</div> <div

嗯？<br /> 要不然，生产wms基片的Ohara公司就得关门了。<br /> </div> <div class="postmsg">哈哈!shanyu,事实胜于雄辩,我做过的行,而且加工的就是要求镀膜的那个面,服吗?</div> <div class="postmsg">To IC5<br /> 古典抛光镀膜成功率和原装的一样吗？</div> <div class="postmsg">当然不能保证100%成功，这主要看抛光师傅的经验了！我说不一样！</div> <div class="postmsg">我的意思你可能是误会了。我是指你们不具有生产 wms系列的能力，而不是简单的光学抛光！</div> <div class="postmsg">那当然，没有生产能力！但国内的冷加工水平也可以达到DWDM的表面要求！只是批量生产可能还是困难·</div> <div class="postmsg">我想问一下在楼上两位，你们说的超光滑表面为什么要求这么严格，是以什么为依据的，据我所知做DWDM的基片有一面必须是自己加工的，难道它也要求很高吗？如果不是那它和第一个面的区别在哪里，谢谢赐教！</div> <div class="postmsg">to ic5:<br /> 你所说的超光滑表面的抛光可以达到0.5nm，请问是如何测试的呢？就是经过镀膜后测试验证的吗？有没有直接的方法进行测试?<br /> 谢谢.</div> <div class="postmsg">有,可到上海光机所测量表面粗糙度!</div> <div class="postmsg">用ZYGO公司的粗糙度仪就可以测量。</div>

VPHG可以应用在波分复用器件上，具有高色散、高效率（>95%）、高带宽、低插入能耗，低PDL（<0.2dB），高稳定性，在C、S、L波段平坦响应等优良特性。</div> <div class="postmsg">说实话，这个东西应该很好做，但要找到合适的耗材。微晶玻璃比较硬，做超光滑加工不难，不要说0.5nm，就是0.2个nm以下也没什么大不了的。<br /> 另外一个，DWDM基片的材料国内是没有的，日本人又不买，所以讨论这个东西好像没有意义。</div> <div style="height200px;"></div> </div> </div> </div> </div></div> </div> <!--autocomment filter by maxnum--> <div class="ft_wp"> <div id="ft" class="
