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)
Additional Content IPC
Glossary
control when referred to light or optical elements, systems or apparatus, covers affecting or directing one or more of the following properties of light: intensity; colour; phase; frequency or wavelength; polarisation; direction; and one or more of the following optical operations: gating; switching or deflecting; modulation.
Limiting references
Devices or arrangements, the optical operation of which is modified by changing the optical properties of the medium of the devices or arrangements
Application references
Devices or arrangements specially adapted for measuring characteristics of light
CPC subdivides this area 2x more granularly than IPC with 4 additional codes.
4 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1985.
