High Temperature Camera Probe

A camera probe, comprising:

• an elongated housing having an external wall made of heat-resistant material enclosing therein an internal space, said housing having a forward opening covered by a window of heat-resistant radiation-transparent material, and a position within said internal space for mounting a camera to receive radiation passing through said window;
• at least one channel for liquid coolant within or adjacent to said external wall, at least over a part of said external wall exposed to elevated temperatures during use of the probe;
• and
• at least one gas exit port adjacent to said window oriented to direct gas passing through said at least one gas exit port to sweep over an external surface of said window,
• wherein said elongated housing comprises a forward part having a longitudinal axis and containing said window, and a rearward part remote from said window, said forward part being movable relative to said rearward part out of initial alignment with a central longitudinal axis of said rearward part, and
• wherein said elongated housing has at least one additional part that is positioned between said forward part and said rearward part and is configured to facilitate movement of said forward part and/or said rearward part relative to one another.
