日立新一代全數字化120kV透射電子顯微鏡HT7800,屬于日立瑠璃系列產品Ruli TEM,操作的一體化和自動化程度都有明顯提高。HT7800系列產品有兩個型號HT7800和HT7830。
HT7800系列產品的**特點是采用日立**設計的第二代雙隙物鏡,很好地繼承了日立120kV-TEM的基本理念,兼顧低倍率與寬視野觀察、高襯度與高分辨率觀察,可在同一儀器上一鍵切換等。集高襯度和高分辨兩種模式于一體,可同時滿足軟材料/納米材料類和生命科學類客戶對電鏡的需求。
HT7800使用高速高靈敏度的CMOS熒光屏相機取代了傳統的熒光屏觀察窗,將 TEM 操作統一于顯示器上,實現透射電鏡操作的全數字化,可以在明亮的室內進行觀察。這樣,既可以保護操作者和樣品,也可以顯著改善操作環境。
