Claim Text:
1. An optical probe comprising: a first end; a second end; an outer housing; an inner housing concentric with the outer housing; a plurality of flow holes within the inner housing at the first end; an optics holder having a low coefficient of thermal expansion within the inner housing between the plurality of flow holes and the second end; a plurality of high temperature optical lenses inside the optics holder between the plurality of flow holes and the second end; a plurality of fiber holders having a low coefficient of thermal expansion inside the optics holder between the plurality of high temperature optical lenses and the second end; a plurality of optical fibers extending from inside the plurality of fiber holders towards the second end and coated in gold or copper to allow the optical fibers to withstand temperatures of up to at least 1120 degrees Fahrenheit; and a high temperature adhesive capable of withstanding up to 2200 degrees Fahrenheit for securing the plurality of optical fibers, the plurality of fiber holders, and the plurality of high temperature optical lenses, so that the optical probe can withstand temperatures of up to 1120 degrees Fahrenheit; wherein the plurality of flow holes are configured to expel gaseous nitrogen across an outer surface of the high temperature optical lenses.
