During 2020 – we have developed a prototype optically corrected zoom lens – a design concept that vastly reduces the moving parts of a zoom lens to just a single push pull movement. This innovation eliminates the need for complex cams and tubes in tubes that are required in traditional zoom lenses. This radical new design shows real promise for use in spaceborne applications and also in hazardous environments.
