Patent ID: 11892618
Assignee: CARL ZEISS MICROSCOPY GMBH
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. The optical arrangement as claimed in claim 9, wherein for setting an intensity pattern and a phase pattern, the control unit is configured:
to set at the liquid crystal elements/mirrors of the first liquid crystal region or lifting micromirror region mutually different phase retardations, which together help form the phase pattern;
to set at the liquid crystal elements/mirrors of the second liquid crystal region or lifting micromirror region phase retardations that are composed of:
A) phase retardations that correspond to those of the liquid crystal elements/mirrors of the first liquid crystal region or lifting micromirror region for forming the phase pattern; and
B) phase differences to the respective phase retardations of the first liquid crystal region or lifting micromirror region for forming the intensity pattern.
