Digital camera for transmission electron microscope

透射/扫描透射电子显微镜（TEM/STEM）能够产生高分辨率图像（在某些情况下为原子分辨率），并提供样品的高分辨率结构和成分信息（来自尺寸小于5 nm的区域）。 这类信息对材料工程和科学研究人员来说是无价的。该申请是为了获得用于TEM/STEM的电荷耦合器件（CCD）相机的资金。 显微镜目前使用照相胶片以TEM模式获得样品的图像和电子衍射图案，即，当使用固定探针时。 虽然胶片产生高质量的图像和衍射图案，但采集过程可能是漫长而乏味的。当前的技术使得数码相机具有足够的分辨率和动态范围以满足大多数成像要求，同时大大减少了成像和处理时间。 此外，研究人员能够立即取得成果，这将提高该设施的利用率。

Transmission/scanning tansmission electron microscopes (TEM/STEMs) are able to produce high resolution images (atomic resolution is some cases) and provide high resolution structural and composition information (from regions less than 5 nm in size) of samples. This type of information is invaluable to materials engineering and science researchers. The application is for funds to obtain a charged coupled device (CCD) camera for a TEM/STEM. The microscope currently uses photographic film to obtain images and electron diffraction patterns of samples in the TEM mode, i.e., when a stationary probe is utilized. Although film produces images and diffraction patterns of high quality, the acquisition process can be lengthy and tedious. Current technology is such that digital cameras possess sufficient resolution and dynamic range to satisfy most imaging requirements, with substantially reduced imaging and processing times. In addition, researchers are able to obtain immediate results, which should enhance utilization of the facility.
