<p>用干涉显微镜啊，我们公司就有代理美国ADE公司的产品，不过比较贵，而且用来看玻璃表面光洁度好象有点过分！<br/></p>
<p>S/D是美国军方制定的光学元件的表面光洁度的标准,定义的比较详细,可以到网上寻找到相关的美军标的详细标准,所谓的与国标比较,没有什么可比性,国标定义的太粗,40/20等于国标三及,是因为美军标通常用的有10/5,20/10,40/20三种,所以有人将它对应国标的三级光洁度,这是错误的,如有疑义的,可详细对照两个标准.粗糙度指的是,在加工过程中,加工表面微观破坏层深度,两者的概念不可混淆.</p>
去看看美军标吧，上面写得很清楚 。想传可是文件太大传不了啊。不好意思啦

<p>光洁度和粗糙度应该是一个概念吧。至于道子点子的问题，应该是表面质量（美）或者表面疵病（国、德）</p><p>以下是引用opticlin7在2006-12-31 19:40:00的发言：p光洁度和粗糙度是两个概念：/pp光洁度相对是比较宏观表面的缺陷，粗糙度是相对微观的表面不平整度/pp1。粗糙度用的不是普通的单频干涉仪，一般是用白光干涉仪，WYKO NT系列，ZYGO newview6000轮廓仪都可以测量。/pp2。粗糙度也有用探针式轮廓仪测量，好象WYKO公司也有生产相关型号/pp/pp/p</p>
<p>４０／６０是美标上指的光洁度标准，４０代表４０＃的麻点，６０代表６０＃的擦痕相当于国标五级光洁度，表面粗糙度指的是未经过抛光的零件表面的面形度．</p>
