CCD CAMERA OPERATED UNDER VERY LOW TEMPERATURE ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a CCD camera capable of observing the state of an object under a very low temperature environment through various narrow routes as occasion demands.

SOLUTION: The CCD camera is operated under the very low temperature environment by mounting a heater and a temperature sensor on the CCD camera operated in only the vicinity of a room temperature to keep the temperature of the CCD camera in an operation temperature range even if a temperature around the CCD camera changes. Since electric wiring is used without requiring vacuum heat insulation, the state of the object under the very low temperature environment can be observed through various narrow routes as occasion demands.
