submillimeter
Below one millimeter
Submillimeter describes measurements or wavelengths smaller than one millimeter.
The term appears most often in astronomy and physics, referring to electromagnetic radiation between infrared and microwave frequencies: submillimeter telescopes, submillimeter observations of distant galaxies.
Also spelled sub-millimeter or sub-millimetre.
