Earlier quoted context omitted.

The only problem is that the camera would not survive the first time you use that oven. High power microwaves happily destroy all manner of electronics.

Surely it can be shielded? IR and microwave wavelengths are nowhere even close to each other. The grill in my microwave door lets through visible light. And the electronics already present in my microwave seem just fine.

Shielding is straightforward; styropyro on YouTube made a ridiculously overpowered oven, 20 kW, was able to film the interior via a small hole, camera was basically fine.

Can't shield the lens, which would be facing the cavity unobstructed.

If you're screwing around with microwave sources, I'll pass on a warning I got from one of my profs. Microwaves will heat your body up, but in a relatively harmless way. e.g. If you microwave your hands a bit, blood flow will transfer that heat out and things will remain pretty okay unless you really overdo it. Your eyes are an exception. They're orbs of aqueous humor that's mostly water, but have relatively little b…

What kind of protective goggles can help here ?

No idea. What the prof meant was to avoid exposure. i.e. Maybe don't lean in so close to get a better look at it while it's on.
