When you want to buy thermal imaging cameras, you need to know the different options available. Thermal imaging cameras have progressed to become cost-effective, viable and critical tools for technicians. Using today’s thermal imaging cameras, technicians can help their organizations avoid expensive downtime and cut repair costs. They can also identify the building’s problems before they worsen.

Close-up on cameras

The interest in infrared technology is growing and a lot of manufacturers are developing new products in all sizes and shapes. It is, therefore, important for managers to know and understand the technology to specify the best camera for a particular application.

Thermal imaging cameras come in three types: long wavelength, mid wavelength and short wavelength. Each of these night vision equipment has its own place depending on use.

Short wavelength

These cameras detect infrared wavelengths in a range of about 0.9 to 1.7 microns. This is close to the visible light spectrum. Short wavelength cameras deliver very high resolution that is relative to the visible light spectrum.

Mid wavelength cameras

These cameras detect infrared wavelengths in about 2 to 5 microns spectral range and they deliver higher resolutions with accurate readings. The pictures aren’t as detailed as those of long-wavelength cameras due to an increased amount of absorption by the atmosphere within this spectral range. Mid-wavelength cameras are used for extremely high-temperature readings.

Long wavelength cameras

These are the most popular cameras and most people consider them when they buy thermal imaging cameras. They detect infrared wavelengths in the range of about 7 to 12 microns and cameras that operate in this range provide a great deal of detail because there is minimal atmospheric absorption. Both mid and long-wavelength cameras provide accurate temperature measurements. They can also produce detailed differences across large or small temperature ranges.
