Inverted Phase-Difference Microscope

The inverted phase contrast microscope positions the light source and objective lens below the sample, converting differences in sample thickness into brightness and contrast through an annular diaphragm and phase plate. It is used to observe transparent living cells and dynamic processes of microorganisms, enabling direct viewing of samples in culture dishes for applications such as cell culture and water quality testing.
Selection
When selecting, consider matching the sample container thickness with a long working distance objective lens. The numerical aperture determines resolution. Choose fluorescence or micromanipulation accessories based on observation needs. Check the alignment accuracy of the phase contrast ring, ensure thermal stability for prolonged live observation, and verify that the operation interface aligns with user habits.
