Hello there. I am working on a project that requires the long-wave IR monitoring of a powder bed. The bed is in a restricted access chamber and therefore optics have to be used to reflect the object. This is where the problem arises, my intention was to use a Enhanced Aluminium mirror to reflect the objects emitted IR into the camera, however the chamber is heated to 178 C therefore the mirror itself emits its own IR. I am using an FLIR E40 IR camera. Doe anyone have any ideas how to tackle the problem?
