Phase-Contrast Optical Microscope

Phase contrast optical microscopes utilize special annular diaphragms and phase plates to convert refractive index differences in transparent samples into contrast in brightness and darkness. They are used to observe transparent specimens such as unstained live cells and microorganisms, revealing details of internal structures in biomedical and material testing.
Selection
When selecting, consider the sample thickness and refractive index range to match the corresponding phase contrast ring. Determine the magnification based on observation needs and check for the PH marking on the objective lens. Ensure the uniformity of the illumination system, and the stage must have a centering adjustment device. Pay attention to preventing mold and cleaning optical components.
