Where does infrared energy come from?

March 6, 2017By Bob BerryGeneral

This is a question that I get asked from time to time. All objects emit infra radiation, the hotter the object, the more infrared energy it emits. It is generated by rotation and vibration of atoms and molecules. The higher the temperature, the faster the movement of the atoms and molecules, and therefore the more infrared is … Read More

Flir T1K camera review

February 27, 2017By Bob BerryGeneral

T1K I have been asked a number of times for my opinion on the T1K, so I have decided to give my opinion. This will be honest, but extremely subjective.

Solar Loading

January 9, 2017By Bob BerryGeneral

I have been asked quite a lot recently about the effect of sunshine on thermography. Strong sunlight will cause solar loading, this means that the sun will heat the objects that it is shining on. While we don’t normally worry about colour in thermography, colour will strongly affect the amount of heat transfer that takes place … Read More

Difficult emissivity measurements

December 19, 2016By Bob BerryGeneral

  I have had several communications from people for whom the basic method for measuring emissivity just doesn’t work. There are various reasons why this can be unsuitable, including not being able to heat the object, or the object temperature being very high, and burning the pvc tape. Here are some suggestions; Firstly we must … Read More

Infrared windows

December 5, 2016By Bob BerryGeneral, Training

Infrared windows are often used to allow us to inspect through an opaque solid material. They are made from various materials and are very useful where no other option exists.
