FrydSpl33n 10 Posted September 14, 2013 When I look through a window with TWS with heat vision on, it does not see through the window. Share this post Link to post Share on other sites
KeyCat 131 Posted September 14, 2013 Actually glass is a pretty good blocker so it may be by design ;) /KC Share this post Link to post Share on other sites

squirrel0311 16 Posted September 23, 2013 (edited) Yep, thermal only sees specific wave lenghts of the light spectrum, the glass blocks the heat signature of anything on the other side because it has it's own signature. Which is why I say we need a Muzzle Thump action that can be used for hitting people or breaking out windows.

Tonci87 163 Posted September 23, 2013 You can´t see through glass with TWS IRL too. Share this post Link to post Share on other sites
bonham 10 Posted September 23, 2013 There are special IR permeable glasses available, made from various metalloid elements except Si. But since most glasses contain Si, they are more or less complete barriers for IR light. Share this post Link to post Share on other sites

That's not why. It's simply opaque to photons at that wavelength. Automotive glass and glass windows are specifically designed to block IR transmissions to help insulate the car / house. Auto glass is also semi opaque to visible light owing to its checkerboard polarization. If you've ever worn polarized glasses and looked at a car, you know what I mean.

Car glass isn't polarised in the sense that polarised sunglasses are (i.e it isn't constructed with a polarising filter). Rather than simply filtering out components of the light that were incident on the glass in a certain polarisation (beyond the natural filtering of horizontal light cause by surface reflection), stress patterns in the glass from the tempering process cause parts of the transmitted light to change polarisation in certain areas. Looking at the window with polarised sunglasses shows these regions where the light transmitted through the windows has, or has not has not had its polarisation changed.

max power 21 Posted September 24, 2013 I stand corrected. I guess the heat elements are checker-like or something. Share this post Link to post Share on other sites
