G02F1/293 - CPC Classification

Classification description:

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 position or the direction of light beams, i.e. deflection by another light beam, i.e. opto-optical deflection
