Scanning electron microscope for high resolution imaging

多伦多大学密西沙加分校（UTM）的研究人员需要一台扫描电子显微镜（SEM）来进行高倍率、高分辨率的成像。校园没有中小企业，其研究设施与多伦多校区（约30公里远）的研究设施是独立的，因此在那里使用中小企业进行研究是不切实际的。我们正在寻求购买一台桌面扫描电子显微镜（SEM），它方便，简单，操作成本低。该装置允许高达20,000倍的放大倍率和以纳米为单位的测量，但也允许为UTM的生物学家，古生物学家和考古学家进行大深度聚焦成像。标准的sem需要有技术支持的特殊安装。然而，所建议的台式扫描电镜需要非常短的学习曲线，不需要技术人员，非常容易使用和维护。因此，个别研究人员可以在需要时使用该仪器。扫描电镜由连接的计算机上的软件控制，可以以各种分辨率捕获图像。台式扫描电镜特别适合于化石、植物组织、昆虫、动物细胞和不需要元素分析的工业产品的检查。目前，我们已经有了在摄影、宏观和微观层面上研究这些材料的设备，但还没有采用拟议的扫描电镜所提供的放大倍率。因此，提出的仪器填补了我们的图像分析范围内急需的空白，非常适合多学科使用。此外，该仪器将成为各学科之间在高倍率下研究超微结构的良好研究桥梁。

Researchers at the University of Toronto Mississauga (UTM) campus require a scanning electron microscope (SEM) for high magnification, high resolution imaging. The campus does not have one and its research facilities are independent from those at its Toronto campus (about 30 km distant) so it is not practical to use SEMs there for our research. We are seeking to purchase a table top scanning electron microscope (SEM) that is convenient, simple and low-cost to operate. The proposed unit permits up to 20,000 times magnification and measurements in nanometers, but also allows for large depth of focus imaging for biologists, paleontologists, and archaeologists at UTM. Standard SEMs require a special installation with technician support. However, the proposed table top SEM requires a very short learning curve and does not require a technician, is remarkably easy to use and maintain. Thus, individual researchers can use the instrument as the need arises. The SEM is controlled by software on a linked computer and images may be captured at a variety of resolutions. The tabletop SEM is particularly well suited for the examination of fossils, plant tissue, insects, animal cells, and industrial products for which elemental analysis is not required. We currently have facilities for the study of these materials at the photographic, macroscopic, and microscopic levels, but not at the magnification provided by the proposed SEM. Thus, the proposed instrument fills a much needed gap in our range of image analysis, and is ideally suited for multidisciplinary use. In addition, the proposed instrument will serve as an excellent research bridge between various disciplines with shared interests in studying ultrastructure at high magnification.
