Abstract
An optical window assembly of an optical sensor of a downhole tool positionable in a wellbore penetrating a subterranean formation. The downhole tool has a housing with a flowline there through to receive downhole fluid therein. The optical sensor is positionable about the flowline to measure light passing therethrough. The optical window assembly includes a tubular sensor body positionable in the housing (the sensor body having a sensor-end and a flanged signal-end with a passage there through), an optical window positionable in the passage of the sensor body to pass the light from the flowline to the optical sensors, a seal disposed about the sensor body, and a backup ring disposed about the sensor body between the flanged signal-end and the seal to support the seal about the sensor body whereby the downhole fluid is prevented from leaking between the seal and the sensor body.
