Thermal Imaging Cameras – How do they work and what are they used for

Thermal imaging cameras can be used in a number of different circumstances to visualise temperature that cannot be seen by the naked eye, there is technology within the cameras that is quite fascinating, as is the numerous applications that they can be used for.

The only drawback of the piece of equipment is that they are very expensive to purchase, but it possible to hire them out which is probably the best option. If you hire test equipment, it means you can use them only when they are needed. This means you can save money and not have a piece of equipment lying around not getting used for most of the year.

Thermal Imaging Cameras

A thermal imaging camera is an infrared or thermo graphic type of camera which forms an image of radiation which to the naked eye is invisible; it does this in a very similar way as a regular camera would take a photograph of visible light.

The camera also takes different wavelengths compared to a normal camera.  A thermal imaging camera captures wavelengths as long as 14,000 nanometres compared to the visible-light cameras which work in a range between 450 – 750 nanometres.
Infrared cameras are not very different compared to digital cameras today. The lens is used to bring in the information, but instead of visible light, it detects radiation. The detected radiation is then converted into electrical symbols which are then combined to form the image. (more…)
