A phase-contrast microscope (or phase-difference microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-contrast microscope, living cells can be studied as they go through the cell division cycle.
HOW IT WORKS
As light goes through a transparent specimen, there may not be anything interesting to see. However, the light undergoes phase changes as it passes through the different parts of the specimen. Unfortunately, the human eye does not notice phase changes. A phase-contrast microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible.
This also works on reflected light microscopes.
What else can I help you with?
What microscope has pH inscribed on the side?
phase contrast
What research microscope is used to see unstained living microbes and intracellular structures?
The microscope that is used to see internal structures of cells in a natural state is the compound light microscope. The microscope has a lens and light that allows it to see the internal structures of a cell clearly.
What microscope shows cells against a bright background and also shows intracellular structures of unstained cells based on their varying densities?
bright-field
What microscope used to study motility of bacteria?
A compound light microscope is commonly used to study the motility of bacteria. This type of microscope allows for high magnification and resolution to observe bacterial motility through techniques like wet mounts or hanging drop preparations. Movement of bacteria can be seen using phase contrast or dark-field microscopy techniques.
You are looking at a cell through a microscope and see that a tetrad has formed which phase of meiosis is the cell in?
If you observe a tetrad under a microscope, the cell is in prophase I of meiosis. During this phase, homologous chromosomes pair up and form tetrads, which consist of four chromatids. This process allows for genetic recombination and crossing over to occur, contributing to genetic diversity in the resulting gametes.
What are the various KINDS of a microscope?
Stereomicroscope, Compound Microscope, Phase-contrast microscope, electron microscope, Scanning-electron microscope, Transmission electron microscope, Confocal-scanning microscope. THESE ARE JUST SOME. :)

When was the Phase contrast microscope invented?
The phase contrast microscope was invented in 1934 by Dutch physicist Frits Zernike. His innovation allowed for the visualization of transparent biological specimens that were previously difficult to see using traditional microscopes.

What does the phase microscope do?
A phase microscope is used to enhance the contrast of transparent or semi-transparent specimens by exploiting variations in refractive index. It allows for visualization of details that may be difficult to see with a standard brightfield microscope, making it useful for observing living cells and tissues.
What are the advantages of an phase-contrast microscope over a compound light microscope?
Can view live samples and observe motility and responses to stimuli
What is different types of microscope?
There are several type of microscopes, mainly, the one that we use in lab is a simple light microscope or a compound microscope. Then we have the phase contrast microscope, fluorescent microscope, electron microscope (transmission electron microscope [TEM] and scanning electron microscope [SEM]), confocal microscope and even dissection microscope the one which we use during dissections.
What are several ways of seeing transparent organelles?
Using a phase-contrast microscope
How many microscope are there?
There are six different types of microscopes used in the life science. There is the light microscope, phase contrast microscope, fluorescent microscope, electron microscope, atomic force microscope, and scanning tunnelling microscope.
What are the phases phase contrast microscope?
phase change refers to the changes in the amplitude, and wavelength of the light when it passes from one medium to the other...
