multispectral = spectral (semi-transparent) = multi + spectr + al
The word is built regularly from multi- plus spectral, but the technical imaging sense is somewhat specialized.
Etymology
Multispectral combines multi- meaning 'many' with the same root as spectrum, which means a 'range of light' or 'colors'. So multispectral describes cameras or scans that use many different types of light to show details the eye cannot see.
