DIFF Subgroup
G02F 1/166

characterised by the electro-optical or magneto-optical effect

Introduced: January 2019

Full Title

Full titles differ between systems:

IPC:

Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > for the control of the intensity, phase, polarisation or colour > based on translational movement of particles in a fluid under the influence of an applied field > characterised by the electro-optical or magneto-optical effect

CPC:

Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > for the control of the intensity, phase, polarisation or colour (G02F1/29, G02F1/35 take precedence) > based on translational movement of particles in a fluid under the influence of an applied field > characterised by the electro-optical or magneto-optical effect

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1990.
