Prism arrangement for digital electro-optical light deflection systems

The invention relates to a deflection prism arrangement for the formation of a dot pattern for digital electro-optical light deflectors, e.g. laser light deflectors, in which the prism angle of each of the sequence of prisms is doubled, the prism apex angle of the double-refracting prisms with large...

Beschreibung
Zusammenfassung:	The invention relates to a deflection prism arrangement for the formation of a dot pattern for digital electro-optical light deflectors, e.g. laser light deflectors, in which the prism angle of each of the sequence of prisms is doubled, the prism apex angle of the double-refracting prisms with larger prism angles being intersected in such a way by the plane in which optic axis of the prism is disposed, which axis is perpendicular to the system axis, that the two partial angles formed with the optic axis of the relevant prism have a ratio between approximately 2/3 and 3/4.
