Spectral Flatness - an overview ScienceDirect Topics
In manufacturing and mechanical engineering, flatness is an important geometric condition for workpieces and tools. In the manufacture of precision parts and assemblies, especially where parts will be required to be connected across a surface area in an air-tight or liquid-tight manner, flatness is a critical quality of the manufactured surfaces. Such surfaces are usually machined or ground to achieve the requi… Web不平度检测,non-flatness measurement 1)non-flatness measurement不平度检测 1.A novel in-situ non-flatness measurement method of wafer chuck in step-and-scan projection lithographic tool is presented.提出一种步进扫描投影光刻机承片台不平度检测新技术。 2)parallelism detection平行度检测 optilock dressing comparable

Height Gage on Columns set up to evaluate flatness. In application, one way to physically measure flatness is to use a height gage, as we can see in Figure 2. To use the height gage correctly, the part to be measured is first placed upon 3 columns with adjustable heights. Then, the height gage is run across the surface while looking ...
