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

Claim 3:
4. The optical arrangement as claimed in claim 1, wherein
a beam path from the polarization beam splitter to the first liquid crystal region or lifting micromirror region is designed such that the first partial beam is incident perpendicularly on the first liquid crystal region or lifting micromirror region and travels back to the polarization beam splitter along said beam path from the polarization beam splitter to the first liquid crystal region or lifting micromirror region;
a beam path from the polarization beam splitter to the second liquid crystal region or lifting micromirror region is designed such that the second partial beam is incident perpendicularly on the second liquid crystal region or lifting micromirror region and travels back to the polarization beam splitter along said beam path from the polarization beam splitter to the second liquid crystal region or lifting micromirror region.
