A microwave viewing device and, more particularly, an arrangement facilitating the internal viewing of a microwave oven during the preparation of a food product or the like in a microwaving process. The viewing device incorporates a tubular support which is extendable through an opening formed in a side wall of a microwave oven, and which extends into close proximity to a food product being subjected to microwave processing in the oven. The viewing device includes a member constituted of telescopable tubular sections; in essence, which member is adapted to be varied in length by adding or removing sections, in dependence upon the size of the food product contained in the microwave oven, and which includes grid structure for supporting an optical viewing device within and in coaxial relationship with the tubular member; with the optical viewing device, such as an endoscope, fiberscope, boroscope or the like, being conducted outwardly from the microwave oven into operative interconnection with a suitable photographic or video recording apparatus. Within the tubular member, the viewing device, which is hereinafter generally referred to as an endoscope, is supported in concentric and coaxial relationship therewith through the interposition, in the annular space between the outer diameter of the shaft of the endoscope and the inner diameter of the tubular member of at least one transversely extending aperture disc component having a plurality of grid-forming through holes provided therein, and which will to a considerable degree reduce the leakage of microwave from the interior of the microwave oven.
