摘要： An improved cryogenic specimen holder for imaging and analysis facilitates imaging at very high tilt angles with a large field of view. A retractable specimen holder tip protects the specimen during transport. An optimized Dewar design is positioned at a fixed, tilted angle with respect to the axis of the holder, providing a means of continuously cooling the specimen irrespective of the high tilt angle and the amount of liquid nitrogen present in the vessel. The Dewar neck design reduces the entrapment of nitrogen gas bubbles and its shape prevents the spilling of liquid nitrogen at high tilt angles. The specimen holder has a retractable tip that completely encapsulates the specimen within a shielded environment internal to the specimen holder body. The cooling and specimen transfer mechanisms reduce thermal drift and the detrimental effects of vibrations.

摘要： An in situ optical specimen holder is disclosed which may be utilized for imaging and analysis during dynamic experimentation. This holder assembly includes a set of focusing and reflection optics along with an environmental cell. Electromagnetic radiation can be used to optically excite the specimen in the presence or absence of fluid. A highly reflective mirror may be used to focus the radiation on to the specimen without the presence of any heating components within the cell. The spot size of the irradiation at the specimen surface can be varied, thus exciting only a specific region on the specimen. The window type cell provides a variable fluid path length ranging from the specimen thickness to 500μm. The holder has the provision to continuously circulate fluids over the specimen. The pressure within the cell can be regulated by controlling the flow rate of the fluids and the speed of the pumps.
摘要翻译：公开了一种在动态实验中可用于成像和分析的原位光学样本保持器。该支架组件包括一组聚焦和反射光学器件以及环境细胞。在存在或不存在流体的情况下，电磁辐射可用于光学激发样品。可以使用高反射镜来将辐射聚焦在样品上，而不会在电池内存在任何加热组分。样品表面的照射点尺寸可以变化，从而仅激发样品上的特定区域。窗型单元提供从样品厚度到500μm的可变流体路径长度。支架具有使流体在试样上连续循环的条件。可以通过控制流体的流量和泵的速度来调节电池内的压力。
