For inspections, many in the nuclear engineering industry are using a combination of thermal imaging and IRISS polymer infrared windows. These provide data collection points that keep the thermographer safe while allowing inspection of the fully energised system.

IRISS is now processing orders for its custom application, CAP Series, windows for two sites in England and one in Scotland. In recent weeks orders for the same products have been received from Bulgaria and Slovenia.  As they are made from a patented polymer, CAP allows the size of the window to match the application.  For example, a CAP window can be specified to allow a thermal camera to image a bus bar or multiple components in a single pass.
