Zeiss AxioObserver & Apotome

The system is built with a Zeiss Axio Observer Z1 inverted fluorescent microscope, fully automated with component recognition to minimize errors. System components include mercury arc lamp excitation, a Zeiss AxioCamMRm CCD camera with 12-bit dynamic range and extended sensitivity in the near infrared, fully automated xyz stage, a complement of objectives from 10x through 100x, 5 installed filter sets for DAPI, FITC, narrow band GFP, Rhodamine, and far red. The Apotome attachment is designed for precise optical sectioning. The Apotome projects a grid onto the image plane, which allows 3 raw images taken. A software algorithm then removes out-of-focus signals based on the 3 raw images.
