The resolution power of: The unaided human eye is about 0.2 mm (200 μm) The light microscope is about … Read more Types of Microscopes

Phase-contrast Microscopy

Phase-contrast Microscopy

Phase-contrast Microscopy Unstained living cells absorb practically no light. Poor light absorption results in extremely small differences in the intensity distribution in the image. This makes the cells barely, or not at all, visible in a brightfield microscope. Phase-contrast microscopy is an optical microscopy technique that converts phase shifts in the light passing through a … Read more Phase-contrast Microscopy
