Mid-IR supercontinuum sources are a new type of source for the 2-4.5 µm spectrum, but their weight, size and power consumption has previously made them unsuitable for mobile sensing. We demonstrate a highly compact supercontinuum source with a weight of <1 kg and a power consumption of <15 W emitting a spectral brightness comparable to that of a synchrotron and covering the entire 1.8-4.4 µm spectrum. We will also discuss challenges and opportunities of working with a broadband source instead of a single line or tunable source and touch upon the future potential for supercontinuum reaching further into the mid-IR
