Morphology
The phrase simply combines 'infrared' (radiation longer than visible red) with 'emission' (the release of something), so its meaning—radiation emitted in the infrared range—is directly derivable from the constituents. This compositional pattern is literal and cross-linguistically common, so a B1 learner who knows both words should understand it.
Etymology
Infrared emission names the invisible 'light' just beyond red that warm things give out. infrared is that 'beyond red' light and emission means 'giving out', so the phrase means the invisible glow warm objects send out and helps devices find heat or living things.
