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(xiàn)的膠膜的均勻性更好的,這里我們就想一個的真理,好的設(shè)備不是一個工件重要,也是每個部件都是很重要的。現(xiàn)在顯示屏領(lǐng)域的顯示屏生產(chǎn)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.
