A Phase Plate with improved heating mechanism for TEM

摘要

The present invention comprises a body portion, one equipped with a carbon film gap closed at the end that is coupled to the TEM column, plate (aperture plate), the heating element, including the body portion and the heat insulating separator insulated connection coupling, O Cry using TEM (cryo) phase plate for improving contrast ratio of an image observed when heating the separator ( In the phase plate), the heating portion, in the TEM column, and is embedded in the body portion so as to be located on the outside of the barrel when combined sealing the body portion, the other end of the separator extends into the interior of the body portion which relates to the contact with the heating unit, a heating structure to improve the phase plate (phase plate). ; TEM distortion caused by the electric field during the heating operation of the phase plate portion 30 by the present invention while eliminating the carbon film can maintain the cleanliness will be able to maximize the cryo observed when compared to the difference in biological samples.
