Cooled and uncooled thermal imaging – see the unseen

Axsys thermal imager

Thermal imagery allows users to find faults, address issues, provide aid and plan ahead in a variety of vital defence, commercial and industrial situations. From military reconnaissance and security scanning to fire rescue and industrial fault identification, thermal imaging can be the difference between success and failure.

Cooled or uncooled technology?

Acal BFi supply the latest in cooled and uncooled technology to provide the best results every time. The right system for you depends on the environment you work in and the nature of your task.

  • Cooled systems – cooled thermal imagers technology implemented in cameras is based on a detector cooled to a temperature close to 77 degrees Kelvin (about -200°C) or lower. The cooling prevents the thermal sensors from being compromised by their own radiation, and once the system has been in use, will need to be re-cooled. These systems are often larger than the uncooled alternative, but offer outstanding image quality and allow the use of longer-range lenses.
  • Uncooled systems – uncooled thermal imagers technology implemented in detectors usually stabilised to temperatures between -30°C to 30°C or not stabilised at all. These imagers do not need to be built into heavy or bulky containers. That means they are often the choice of military or security organisations that value lightweight equipment over image clarity, because uncooled thermal images are not as sharp or as defined as the cooled option.

Acal BFi thermal imaging systems

We use our experience and understanding of thermal technology to help you make the right choice of thermal imager for your needs. We can recommend both cooled and uncooled technology and give you the before- and after-sales service you need to keep your operations on track.
