Coagulopathy (or bleeding disorder) is a medical condition characterized by the inability of blood to coagulate or clot (i.e., hypocoagulation ).

How is a confocal microscope different?

The main difference between confocal microscopy and a standard fluorescent microscope is the presence of pinholes that are able to exclude photons coming from a different focal plane. (A) Light emitted by a laser source pass through a pinhole and is directed by a dichroic mirror to the sample.

How does a light microscope work?

The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective lenses to enlarge the image formed.

What are the advantages and disadvantages of light microscope?

Advantage: Light microscopes have high magnification. Electron microscopes are helpful in viewing surface details of a specimen. Disadvantage: Light microscopes can be used only in the presence of light and have lower resolution.

What is the difference between light microscopy and confocal imaging?

While the entire field of view is illuminated during confocal imaging, anything outside the focal plane contributes little to the image, lessening the haze observed in standard light microscopy with thick and highly-scattering samples, and providing optical sectioning.

How does confocal microscopy work?

Instead of exciting the entire sample at once with collimated light, confocal microscopy scans a focused point of light back-and-forth across the sample to create an image sequentially. This design allows out-of- focus light to be blocked with a small ~[s um aperture called a pinhole.

What is the difference between a point and confocal microscope?

In contrast, a confocal microscope uses point illumination (see Point Spread Function) and a pinhole in an optically conjugate plane in front of the detector to eliminate out-of-focus signal – the name “confocal” stems from this configuration.

What is the difference between a confocal microscope and CLSM?

Light travels through the sample under a conventional microscope as far into the specimen as it can penetrate, while a confocal microscope only focuses a smaller beam of light at one narrow depth level at a time. The CLSM achieves a controlled and highly limited depth of field.
