The Altius satellite carries a high-resolution imager that observes ozone from side-on, at Earth's limb or atmospheric boundary. This limb-sounding technique allows ozone to be viewed at different altitudes, thereby providing vertical profiles of different ozone concentrations. The instrument uses three independent spectral imagers that operate in the ultraviolet, visible and near-infrared, achieving global coverage in a three-day revisit cycle.

This 3D visualisation of the Altius Instrument, details the inner workings of the three independent channels, highlighting key moments of interaction of the light path and its progression within the instrument.
