Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.

August Kohler
What is confocal microscope?
Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of adding a spatial pinhole placed at the confocal plane of the lens to eliminate out-of-focus light. cited works: wikipedia

What type of microscopy is the negative stain similar to?
The darkfield microscope. "darkfield microscopy"
How is spirochete activity seen?
observation with dark-field microscopy .
What kind of technology does bright field dark field and phase microscopes use?
microscopy
What are Applications of bright field and dark field microscopy?
microscope is used to see small objects
What does FESEM mean in electron microscopy?
Field Emission Scanning Electron Microscopy
Why use fluorescence microscopy for bacillus anthracis?
Perhaps fluorescence would be used because B. athracis has a cell wall making it difficult to visualize the details of the cytoplasm by simple bright field microscopy. Flourescence allows for labeling of specific entities, and "cold" illunimation of those entities against a dark field.
What are the purposes of bright field microscopy?
The purpose of bright field microscopy is to provide a simple, yet effective, technique for use in observing microscopic properties of samples.
What has the author R E Thurstans written?
R. E. Thurstans has written: 'Field-ion microscopy and related techniques' -- subject(s): Bibliography, Field ion microscopy, Field ionization mass spectrometry
What is the difference between phase-contrast microscopy and bright-field microscopy?
Phase-contrast microscopy is the observation of internal structures of living microbes where as bright field microscopy is the observation of killed stained specimens and naturally colored live ones.
How is diagnosis for yaws conducted?
using a technique called dark-field microscopy. This often allows the spirochetes to be identified. They may also be identified in fluid withdrawn from swollen lymph nodes
Gram stain of lymes disease?
Lyme Disease is caused by Borrelia burgdorferi. This is a spirochete bacterium with a gram negative cell wall structure. These organisms are best viewed by dark-field microscopy.
