Title:
OPTICAL ARRANGEMENT AND METHOD FOR LIGHT BEAM SHAPING FOR A LIGHT MICROSCOPE
Document Type and Number:
WIPO Patent Application WO/2019/206651
Kind Code:
A3
Abstract:
The invention relates to an optical arrangement for light beam shaping in a light microscope, comprising a first and a second liquid crystal region, each of which has a plurality of liquid crystal elements which can be switched independently of one another and by which a phase of incident light can be variably changed. A first polarization beam splitter (10) is arranged in such a way that incident light (1) is split in a polarization-dependent manner in reflection light (1A), which is reflected in the direction of the first liquid crystal region (30A), and in transmission light (1B) which is transmitted in the direction of the second liquid crystal region (30B). The first or a second polarization beam splitter (10, 11) is arranged such that the reflection light (1A) and the transmission light (1B) are combined into a common beam path after phase modulation through the liquid crystal regions (30A, 30B).
