一. FastScan系列CCD相机 包括FastScan-F114/-F114T及FastScan-F214/-F214T两类快扫描相机。 主要特点: 1. 二合一功能:同时具备高分辨率扫描CCD相机和快扫描CCD相机的视频输出功能。可变的机械结构设计可使它安装在各种厂家(JEOL、FEI、Hitachi…)制造的所有型号的透射电镜上。闪烁体性能优异,应用在100 ~ 400 KV的高压下,有高分辨率优化型(HR)和高敏感度优化型(HS)两种标准类型。闪烁体和CCD传感器的连接方式为光纤耦合,可收集更多的的光子信号。 2. 独特的CCD冷却方式:与透射电镜的真空分离,采用Peltiel效应冷却的CCD芯片位于单独的真空室中;而闪烁体的表面温度接近室温。这种设计避免了污染,同时也可以在不关闭CCD相机时对透射电镜的相机室进行放气,更换底片等操作。 3. 具有防止CCD中邻近电荷交叉干扰的功能,便于采集衍射花样。 4. 功能强大的图像采集、分析软件包EM-MENU 4.0: · 实时图像处理功能,对实时图像扣除噪音,使其对比度好,视场均匀;此外,同时进行“Power spectrum”图谱计算,实时校正聚焦,像散和放大倍数。 · 图像无缝拼接(蒙太奇),通过软件自动控制束流偏转和图像偏转线圈,分别在X,Y方向连续采集多张图像,然后采用图像强度补偿的方法进行亚像素精度级图像拼接,可以得到与底片尺寸相当的视场范围图像。 · 精确控制TEM电子光学系统,对电镜进行自动聚焦,自动消像散,校正量角器,“Low-dose”等操作。软件自动通过对中,平移,倾斜校正等从而校正样品倾斜后图像的焦距变化以及图像平移。 · 三维重构,通过自动采集系列倾斜角度的图像,然后通过电子断层成像软件,对图像进行对中,组合,从一系列二维图像中重构出三维结构信息。 · 安装位置灵活 FastScan-F114具有灵活可变的安全设计,可以按照不同用户的要求安装在不同的位置。此外用户也可以配置与透射电镜不同位置链接的法兰盘,从而在不同时期将F114安装在不同的位置,下图表示为F114的不同位置的安装型号。

FastScan-F114/-F114T (1K*1K)![]() FastScan-114 represents a new generation of CCD cameras, combining the superior quality of a slow scan CCD camera with the fast frame rate of a video camera.It is available as On-, Near- and Off-Axis Version.
The FastScan-F114 is available in the following designs: F114T:On-axis, with 2:1 tapered fiber optics. Increased field of view and resolution. Fiber optical coupling of the electron-sensitive layer (scintillator) with the CCD sensor increases the amount of light collected in comparison with lens-optical coupling and the sensitivity of the camera as a result. The tapered fiber optics enlarges the field of view to 29mm x 29mm and increases the resolution. F114NX:Near-axis, compatible with post-column filters, PEELS, or other TVIPS on-axis cameras F114FX:Off-axis, compatible with post-column filters, PEELS, or on-axis cameras (FEI/Philips) |
