Abstract

This invention relates to a camera assembly (10) for the inspection of passageways. In particular this invention relates to a camera assembly for the inspection of wellbores and designed to operate in high temperature environments. A camera assembly for the inspection of wellbores comprises an elongate housing (12) having a first end (30)and a second end (42) and, extending between the ends, a side wall comprising an inner wall (22) and an outer wall (24), with a vacuum formed between the inner and outer walls; an elongate relay lens (52)having a first end (56) and a second end (62), the relay lens being located within the housing; an optically transparent window (46) located at the first end of the relay lens; an image sensor (48) located at the second end of the relay lens for capturing an image of an object viewable through the relay lens and window; and a light source (16) arranged to emit light from the housing, for illuminating the viewable object.
