INFRARED DETECTING DEVICE

摘要

PURPOSE:To prevent a Dewar which incorporates an infrared detecting element from breaking by fixing the Dewar to the expander of a refrigerator which cools the infrared detecting element across an elastic body. CONSTITUTION:The elastic body 13 is interposed between the Dewar 2 and expander 6, so this elastic body 13 deforms by vibrations from the expander 6 to absorb the vibration energy of the expander 6. The elastic body 13 reduces the vibrations transmitted to the Dewar 2 and cuts them off. Consequently, the Dewar 2 is prevented from breaking owing to the vibrations that the expander 6 generates.
