Thermal Imaging Frequency Range

Definition and relationship to the electromagnetic spectrum.

Thermal imaging frequency range.

All objects warmer than absolute zero 273 c 459 f emit infrared radiation in the mwir and lwir wavelengths 3µm 14µm in an amount. There is no real maximum range depending on the wavelength and what you are looking through. Mid infrared will have a limit when looking through the atmosphere due to water absorption but the longer waves over 8 microns and the 3 5 micron ran. Thermal technology has advanced far enough that a good quality thermal imaging camera is small enough to fit in our pocket and attached to your cellphone or tablet.

Find hidden problems take accurate temperature readings and confirm repairs were done correctly with the help of the 4 800 80 x 60 pixel infrared resolution and flir multi spectral dynamic imaging msx enhancements. Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers nm to 1 millimeter mm. The thermal imaging industry has evolved drastically since its beginning when thermal cameras were unwieldy bulky heavy and outrageously expensive. The flir e4 thermal imaging camera is an easy to use troubleshooting tools for building electrical and mechanical applications.

The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision which operates in the visible light and near infrared ranges 0 4 to 1 0 μm. What is thermal or infrared imaging. This range of wavelengths corresponds to a frequency range of approximately 430 thz down to 300 ghz below infrared is the microwave portion of the electromagnetic spectrum. Sometimes referred to as flir cameras they produce an image that portrays objects using their temperature instead of their visible properties.

Flir systems offers a wide range of thermal imaging cameras. This article explains thermal infrared imaging the infrared spectrum and the different infrared cameras used. Whether you use thermal imaging for an inspection of large industrial installations or for an inspection of a fuse box in a domestic residence flir will have just the right thermal imaging camera for you. So how does thermal imaging see heat.
