ETD-100AF型高真空熱蒸發(fā)鍍膜儀

采用電阻式蒸發(fā)原理，利用大電流加熱鉬舟或鎢絲藍(lán)或固定支架上的鍍膜材料，使其在高真空下蒸發(fā)，沉積在被鍍樣品上以獲得**鍍膜效果。 適用范圍： 電子顯微鏡樣品制備和清潔光欄，以及科研、教學(xué)和企業(yè)中的實(shí)驗(yàn)活動(dòng)、工藝試驗(yàn)。 使用了大抽速、高壓縮比、自然風(fēng)冷卻復(fù)合分子泵，確保噴鍍時(shí)能夠迅速抽掉蒸發(fā)源和樣品放出的氣體；正常情況下噴鍍室內(nèi)極少有油蒸氣回流，非常清潔。

配有高位定性的飛躍真空泵，渦輪分子泵

ETD-100AF is a high vacuum thermal evaporation type small film coating machine. By using the principle of resistance evaporation， the coating material on the molybdenum boat or tungsten blue or fixed bracket is heated by high current， so that it is evaporated under high vacuum and deposited on the plated sample to obtain the best coating effect. Scope of application: Sample preparation and cleaning of optical microscope， as well as scientific research， teaching and experimental activities and process tests in enterprises. A compound molecular pump with large pumping speed， high compression ratio and natural wind cooling is used to ensure that the evaporation source and the gas from the sample can be removed quickly when the spray plating is sprayed.
