As long as we're being technical, vacuums don't crush things. Unopposed atmospheric pressure crushes things. :laugh:

But I agree, there has to be some air in between the lenses. I wouldn't be suprised if it's a bit below atmospheric pressure, making it a partial vacuum, but there's got to be some gas in there.


Yeah, that's what I meant. :P

thermal lenses are the leftover remains of ancient cyclops giant knee caps.
those knee caps are removed from ancient sky cave and then treated with unicorn powder and elf spit to create an intangible field of pure negative fog energy.

that or a wizard alien made em..


that science crap you are all blabbering about, since when has science ever proven anything


Yeah, that's what I meant. :P

Hmmm... I've always been told it was a vacuum. The guys at the JT booth at D-Day said that too but that don't mean squat. lol. Maybe it's some kind of gas. If it was just a gap of air then it seems like having the seal leak wouldn't cause them to go bad. Now, I'm gonna have to find out for sure.

I just saw a post on PBN that said the air space between the lenses is purged with Nitrogen before the lenses are sealed together but I can't find anything to back that up. This is interesting.

I saw another site that said some thermal windows use argon gas. Maybe that's it.

I've been searching some more and can't find anything definite. Somebody find out!!lol

HAHAHAHA It's killin Dvl!!

An air pocket would allow for a temperature differential between lenses. IE Outside air VS inside. The air pocket serves as an insulator. A leak in the lens would mean a breach of the air pocket and reduce the insulation factor.

But if it's just regular air wouldn't it transfer hot and cold really easily and fog accordingly? There's got to be something in there. CRAP!! I can't find anything. ..........eats thumb :tup: while rocking back and forth in a corner... :dry:

Not necessarily. Think about it. In the winter you dress in layers. Why? Because it creates pockets of air that keep you warm. The air insulates you from the cold.

The air is simply insulation, That's how your hair keeps you warm, it traps air. However, a thermal lens could have some small amount of vacuum pressure as well, but that's not what keeps the thermal lens from fogging up.
