<p>Cryostatic device for characterising sensors at varying temperatures with low stray radiation. It comprises means for accurately stabilising the temperature of the fluid cooling a cold head (4), in particular by virtue of the design of the pipe (101) containing the supply duct (109) and the removal duct (112). It also comprises means (screen 31 covered with an absorbent coating) around the body to be characterised. Application, in particular, to infra-red sensors. <IMAGE></p> |
