ABSTRACT:
An inner vessel having a truncated triangular volume is spaced from an outer housing of similar shape to form a chamber therebetween. A thermally conductive strap is connected at one end to the vessel at its other end to a cold finger tube extending into the chamber. The vessel contains liquid nitrogen and is secured in spaced relationship from the outer housing by a fiberglass liquid nitrogen fill tube. An electronic assembly for processing signals generated by the detector cooled by the cold finger are aligned with the cold finger external the dewar housing. The dewar accommodates entry port angles between zero and 60.degree. for different microscopes without physical interference with the microscope housing and attachments.
