MICROSCOPIC IMAGING OF PROPERTIES OF ROOM-TEMPERATURE OBJECTS

摘要

A cryogenic apparatus for microscopy of physical properties of an object including a thin, stiff, transparent substrate or window (28) within the outer wall of the vacuum space (18) of a dewar and a cryogenic sensor (72) within the vacuum space and spaced very close distances to the window (28). This construction allows for positioning a sample for measurement outside of the vacuum space, at room temperature or higher and for microscopy of physical properties of the sample (91) by monitoring the output from the cryogenic sensor as it is scanned along the surface of the sample (91).
