Zeiss Axio Observer 7 Inverted Microscope with Apotome .2 is an inverted microscope with transmitted (brightfield/phase/DIC) and fluorescence illumination. This unit has a motorized Z-axis for optical sectioning. The Apotome attachment allows for structured illumination, which eliminates out of focus/scatted light. Fluorescence filters include DAPI, GFP, and TexasRed. Digital cameras= 6 MP Axiocam 506 monochrome and 5 MP Axiocam 105 color.
Please use this guide or the Thermofisher Fluorescence SpectraViewer to determine which fluorophores will work with our filter set.

* WD = Working distance, which determines the depth of focus
* Please request 5x objective if need, it floats between this microscope and the confocal in the ILSB.
