Thermal sights...

[antecedent]

Try my hand at stupid questions here... can you see paper targets under thermal sights? Or rather, can you read/see what’s printed on them?

My first guess would be no, based on the images I’ve seen and what little I know about how they work... something like... you could see the paper itself as a rectangle thing, but probably couldn’t read anything on it?

It that’s the case, what do they use for calibration/resolution charts like for conventional optics/camera lenses? How do you zero? Are there targets with different materials just for use with thermal?

You can’t read things with thermal unless they are a different temp from surrounding materials. Just remember that the image is built by contrasting temperatures so it’s not like looking through a normal scope.

many people use hand warmers to zero them. Aluminum foil also works and my favorite are those aluminum circle lids you get from Mexican takeout food.
