MWIR (Mid-Wave Infrared)

Mid-Wave or MWIR Infrared is a subset of the infrared band of the electromagnetic spectrum, covering the wavelengths ranging from 3µm to 5µm (3000nm to 5000nm). This is the radiant heat that our cooled thermal imaging cameras see.

MWIR thermal cameras are capable of achieving the longest range detection for thermal infrared surveillance cameras and are often cooled via cyro-cooler, allowing them to offer extreme range with high contrast and little noise.

For more information about MWIR imaging for surveillance, please see our Thermal Imaging technology page.
