日立新一代全数字化120kV透射电子显微镜HT7800,属于日立瑠璃系列产品Ruli TEM,操作的一体化和自动化程度都有明显提高。HT7800系列产品有两个型号HT7800和HT7830。
HT7800系列产品的**特点是采用日立**设计的第二代双隙物镜,很好地继承了日立120kV-TEM的基本理念,兼顾低倍率与宽视野观察、高衬度与高分辨率观察,可在同一仪器上一键切换等。集高衬度和高分辨两种模式于一体,可同时满足软材料/纳米材料类和生命科学类客户对电镜的需求。
HT7800使用高速高灵敏度的CMOS荧光屏相机取代了传统的荧光屏观察窗,将 TEM 操作统一于显示器上,实现透射电镜操作的全数字化,可以在明亮的室内进行观察。这样,既可以保护操作者和样品,也可以显著改善操作环境。
