還是一個最重要的工件就是運動平臺，若你的平面精度達不到，也是很難實現的膠膜的均勻性更好的，這里我們就想一個的真理，好的設備不是一個工件重要，也是每個部件都是很重要的。現在顯示屏領域的顯示屏生產TFT、OLED也用這種方式， 因為顯示器對膠的要求不是很高。

三、彎月面涂膠方式　Meniscus　Coating

     NEW optical coating materials and laser technologies have created a need for large optics with uniform, ultrathin coatings that are applied from liquid solutions. Such devices are used, for example, in high-power laser systems at LLNL and elsewhere. To manufacture these optics, coatings a micron in thickness or less need to be deposited with extreme uniformity—to within a few percent—across the entire clear aperture, which can be on the order of a square meter in size. Micron- and submicron-scale films have been traditionally applied from liquid solutions by spin coating or dip coating. However, spin coating massive optics at the high rates needed to achieve a uniform film is not practical and wastes the coating fluid. Dip coating requires large volumes of expensive coating fluids and risks intercontamination of materials in a multilayer application.
