NanoCalc 反射膜厚测量系统
 |
薄膜的光学特性主要有反射和干涉。NanoCalc薄膜反射测量系统可以用来进行10nm -250um的膜厚分析测量，对单层膜的分辨率为0.1nm。根据测量软件的不同，在1秒钟内可以分析单层或多达到10层的膜厚。 |
产品特点
- 可分析单层或多层薄膜；
- 分辨率达0.1nm；
- 适合于在线监测；
使用原理
常用的两种测量薄膜的特性的方法为光学反射和投射测量、椭圆光度法测量。NanoCalc利用反射原理，通过测量宽光谱范围内的反射率曲线来进行膜厚测量。
查找n和k值
可以进行多达十层的薄膜测量，薄膜和基体材质可以是金属、电介质、无定形材料或硅晶等。NanoCalc软件包含了大多数材料的n和k值数据库，用户也可以自己添加和编辑。
