Zeiss Observer Z1 – inverted widefield microscope

The Observer Z1 is an inverted microscope from Zeiss allowing brightfield, phase, DIC, and fluorescence microscopy. It is also equipped for live cell imaging experiments. Except the stage the system is fully motorized, and all components are controlled by the ZEN 2012 (blue) software. It is able to run multidimensional experiments including multichannel acquisition, z-stacks, and time-lapse. Since it is an inverted microscope, it is suitable for imaging both live cells and fixed samples. It is equipped with a highly sensitive black&white fluorescence camera.
