Phase-contrast microscopy. Phase contrast is an optical contrast technique for making unstained transparent objects visible under the optical microscope. An annulus aperture is placed in the front focal plane of the condenser and limits the angle of the penetrating light waves.
These are the basic principles of microscopy that a researcher must have an understanding of when operating core bioimaging facility instruments, in order to collect high‐quality images. © 2020...
