超高分辨208HR鍍膜系統(tǒng)是現(xiàn)在針對場發(fā)射電鏡非導(dǎo)電樣品鍍膜處理以及高性能電極薄膜制備的的解決方案。為了減小噴鍍顆粒尺寸對成像分辨率影響,208HR提供一套全系列的鍍膜靶材材料和的膜厚鍍層控制條件,以達(dá)到無顆粒鍍膜效果。而為了更小優(yōu)化非導(dǎo)電樣品表面充電的效果,208HR的特殊樣品臺設(shè)計(jì)和大范圍的操作壓力提供了高精度的鍍膜一致性和統(tǒng)一性。 高低樣品室的配置也提供了更為方便的工作距離調(diào)整。
Cressington 208HR High Resolution Sputter Coater
The 208HR High Resolution Sputter Coaters from Cressington offer real solutions to the problems encountered when coating difficult samples for high resolution FESEM imaging. High resolution FESEM applications need extremely thin, grain-free, uniform coatings to eliminate charging and to improve contrast on low density materials.
In order to minimize the effects of grain size the 208HR offers a full range of coating materials and gives unprecedented control over thickness and deposition conditions. The 208HR Turbo Pumped High Vacuum System offers a wide range of operating pressures allowing precise control of both uniformity and conformity of the coating, minimizing charging effects. The HIGH / LOW chamber configuration allows easy adjustment of the distance from target to sample.
