Introduction to Phase Contrast Microscopy MicroscopyU
The first steps necessary to prepare the microscope for Kohler illumination involve basic procedures necessary to observe a specimen under brightfield conditions. First, if the condenser contains phase annulus rings, differential interference contrast prisms, or other masks and filters, rotate the turret to the brightfield aperture, which should be open and not house a filter or prism. Second... In the system shown at the right, the phase condenser has five settings that you can rotate through (10x, 20x, 40x, 100x and BF) BF is "brightfield" with no phase. To set up your microscope for phase optics, you first set it at BF and focus on the specimen. Adjust the height of the condenser for optimum image quality.

How To Set Up Phase Contrast Microscopy

Phase contrast microscopy is now capable of converting a difference in refractive index into a difference in brightness. The optics of the phase contrast microscope would make objects appear brighter or darker (depending on the optics used), thereby increasing their color contrast with the surrounding mounting medium.

  • Setting up the phase-contrast microscope Set the microscope up, in proper adjustment for Kohler illumination for bright-field microscopy, using a well-stained
  • Phase contrast is a microscopy method that speeds up the direct light path in order to cause destructive interference patterns in the viewed image. Phase contrast microscopes are useful for viewing details in bacteria, protozoans, blood cells, sperm tails and a variety of unstained cells.
  • intrinsically low contrast between object and its surroundings - live with it, or use contrast enhancement methods (such as differential interference contrast, phase contrast, dark-field illumination), or stain the specimen, or use mountants that differ significantly in refractive index from the specimen.
  • In this study, we introduce a scanning transmission electron microscopy technique combining a pre-specimen phase plate designed to produce a probe with structured phase with a high-speed direct electron detector to generate nearly linear contrast images with high efficiency. We demonstrate this method by using both experiment and simulation to simultaneously image the atomic-scale structure of
