ABSTRACT:
A measuring instrument for receiving radiation through an opening in a housing and having a protective shield member across the opening. The protective shield member is sealed against the housing to project a flexible contact portion at above ambient pressure for contacting and conforming to the surface of an object. A flexible dome on the protective shield member can pump air into the protective shield member to provide the desired internal pressure. The protective shield member is relatively thin and reaches thermal equilibrium with the object in a relatively short period of time, when the measuring instrument is a radiation thermometer.
