Optical Assembly and Light Microscope

摘要

The invention relates to an optical assembly for spectral filtration of light, having a plurality of filters which are permeable to light of different spectral ranges, a filter selection mirror which can be moved for selectable deflection of light to different optical paths to the different filters, and an output mirror which can be moved to guide light coming from one of the filters to an optical path which is the same for all the filters. The optical assembly is characterized according to the invention in that in each case at least one stationary deflection optical system is provided for each of the optical paths to the different filters to guide light from the filter selection mirror to the respective filter and/or light from the respective filter to the output mirror, and the stationary deflection optical systems are arranged so that optical path lengths on the different optical paths from the filter selection mirror to the output mirror are equal. The invention further relates to a light microscope having an optical assembly according to the invention.
