When using the device, defective (dead) pixels may appear on the microbolometer. These are bright or dark points of a constant brightness that are visible on the image.
Defective pixels on the microbolometer can increase in size relative to the digital-zoom power.
The Thermion 2 thermal riflescope allows the user to remove any defective pixels on the display, as well as cancel removal, via the device’s firmware.
