Titles differ between systems:

IPC: Optical devices or arrangements for the control of light using movable or deformable optical elements

CPC: Optical devices or arrangements for the control of light using movable or deformable optical elements (control of light by modification of the optical properties of the media of the elements involved therein G02F1/00)
