A term referring to the conventional brightfield lighting method in microscopy, where the specimen is illuminated by a uniform, full-spectrum white light from below, and the background of the image appears bright white.
read more about white field illumination ...Used in contrast to specialized techniques like darkfield illumination (where the background is black) or phase contrast (which enhances density differences).
It is the simplest and most common method of illumination, suitable for viewing naturally pigmented or stained (color-contrasted) specimens.
Refers to the background light of the perimeter dome. Standard perimetry uses a white or slightly yellow background light of $31.5 ext{ apostilbs}$ (asb) for testing.
Because the background (the field) remains brightly lit, and the specimen is viewed in contrast to this bright background.
No. Unstained, clear (transparent) specimens often show very low contrast and are better viewed using phase contrast or darkfield microscopy.
A specific technique used to align the white field illumination in a brightfield microscope to ensure uniform, glare-free light across the entire specimen.
