Inverted microscopes offer several key advantages:

Greater Working Distance: The objectives are located below the stage, allowing for a significantly larger working distance compared to upright microscopes. This is crucial for:

Accommodating larger containers.  

Performing manipulations above the specimen.

Using micromanipulation tools.

Easier Sample Access: The open space above the stage provides easy and unobstructed access to the sample for:

Manipulation.

Reagent addition.

Experimental procedures.

Improved Ergonomics: The inverted design often provides a more comfortable and ergonomic viewing position for the researcher, reducing strain and fatigue during extended observation periods.  

Enhanced Suitability for Live Cell Imaging: The design is well-suited for long-term observation of living cells, minimizing disturbances to the culture environment.  

Versatility: Many inverted microscopes can be equipped with a wide range of accessories and techniques, such as:

Fluorescence microscopy

Phase contrast microscopy  

Confocal microscopy

Live cell imaging systems
