Used ZEISS Axio Observer D1

Zeiss Axio Observer D1 Inverted Phase Contrast Fluorescence Encoded Binocular Microscope (Catalog Number: 431006)

The Zeiss Axio Observer D1 is a semi-motorized, encoded inverted fluorescence microscope designed for research applications requiring high-quality imaging with repeatable settings. Combining the reliability of manual operation with encoded optical components, the Observer D1 helps users track key configurations like objective changes and fluorescence filter cube positions for reproducibility and documentation.

Configured with a binocular viewing head, this model is ideal for users performing live-cell imaging, phase contrast, and routine fluorescence microscopy without the need for full motorization. Its modular architecture and encoded components make it a reliable platform for consistent, high-contrast results.
