Gibsonm Posted May 17, 2022 Share Posted May 17, 2022 Yes that's because most military TI systems can't detect heat through glass. The glass forms a barrier so the TI reports nothing. Yet another reason to alternate between using the TI and the day sight. 1 Quote Link to comment Share on other sites More sharing options...

F.T Posted May 17, 2022 Author Share Posted May 17, 2022 Thank you. I was wrong to think that the infrared wavelengths used for thermal imaging could pass through the glass. 0 Quote Link to comment Share on other sites More sharing options...
Members Ssnake Posted May 17, 2022 Members Share Posted May 17, 2022 With special glass types and Germanium coating, it works. An essential component for the feasibility of thermal imagers as sensors. Vacuum-separated double-pane windows OTOH are effective means to keep a home insulated. 0 Quote Link to comment Share on other sites More sharing options...
