Inverted Phase Contrast Microscope

The inverted phase contrast microscope uses an annular diaphragm and a phase plate to alter the phase difference of light, converting the refractive index differences of transparent samples into variations in brightness and contrast. It is used for observing unstained transparent specimens such as living cells and microorganisms, enabling direct observation of samples in culture dishes in the fields of biology and medicine.
Selection
When selecting, consider sample thickness and culture containers to ensure sufficient working distance of the objective lens. Match the phase contrast ring with the objective lens magnification based on observation needs, and check the uniformity of the light source and the operability of the centering mechanism. Confirm that the stage can accommodate experimental vessels and that the mechanical structure meets the stability requirements for long-term use.
