ATN Thermal and Night Vision

[Regulator23]

I am new to the forum but read some things already that indicated there might be people that can help me. I own an ATN Thor 4 384-1.25-5x thermal and have been having a lot of fun with it. I’ve never owned a night vision scope but hear target ID could be much better than using thermal. I found a used ATN X-sight HD 5-18 night vision scope and bought it. The guy included an extra lens and said the x-sight could be turned into thermal by installing it. The lens looks exactly like the lens on my Thor 4 384.

I’ve included pictures of the ATN x-sight scope and the lens. The thread size of the lens is right at 60mm. So is it possible to install that lens on the x-sight scope and use it as a thermal? I haven’t tried to see if it will even fit and wanted to check before I did anything like that. It just seems like the technology inside the scope should be different for thermal, but I have no clue.

If it won’t work like that, I guess I could just keep it as a backup lens for my Thor 4. Which leads me to another question. If I wanted a 4.5-18x lens for my Thor 4, is at as simple as buying that lens and switching it out? Are there firmware, etc. Type changes that would have to be done?

Sorry for the long-winded question but I hope you see what I’m asking. Thank you
