Constructional details

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 > Constructional details

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 > Constructional details

Of 8 combined children, 7 exist in both systems.

1 codes are CPC-only extensions.

Note: 1 CPC extensions are marked as secondary classification only.

IPC defines codes here since 2019.
