Demonstration Video
Action on the infrared spectrum -- kryo 20N IN
IR rejection test under controlled environment
The infrared lamp (75W) heats two steel plates connected to a thermometer, the whole being placed behind a glass plate (4mm).
The adhesive film presented on this page is stuck on the right side.
Actual test duration: 30 min
