Lumus Lumus is an Israeli company which designs optical engines for AR/MR and head mounted display (HMD) devices. These optical engines are composed of a display and reflective (geometric) waveguide - Lumus' key expertise are in the design of these waveguides, which can expand the exit pupil in two dimensions. These waveguides, originally invented by Lumus, are mass-produced via license by original design manufacturers (ODM) partner firms, although Lumus has its own smaller production line for military products and R&D work.
