Microscope fluorescence filter system for use during microscopic analysis, has divider-substrate and/or blocking filter substrate that is adjustable such that beam deflection in system opposite to optical axis is minimized

摘要

The system (1) has a dichromatic beam splitter (3) and a blocking filter (4) that are formed as a thin film system with a thin layer on a transparent substrate. A divider-substrate of the beam splitter and/or a blocking filter substrate is formed as a wedge plate with a wedge angle. The divider-substrate and/or the blocking filter substrate is adjustable such that beam deflection in the system opposite to an optical axis (7) is minimized.
