Yes, a bright field microscope can be used to view living specimens, but it may not be the best choice depending on the specimen's transparency and how much detail needs to be observed. Dark field or phase contrast microscopy may be better for observing living specimens without staining.
What else can I help you with?
What are the characteristic of bright field microscope?
A bright field microscope is a type of light microscope that uses light from below the specimen to illuminate and create contrast with the specimen. It produces a dark image of the specimen against a bright background. Bright field microscopes are commonly used in biology labs for observing stained or naturally pigmented specimens.
Name three variation of the light microscope and a common use for each?
Bright-field microscope - commonly used for general observation and identification of stained biological samples. Phase-contrast microscope - useful for visualizing transparent and unstained living cells in microbiology research. Fluorescence microscope - ideal for detecting and imaging fluorescently labeled molecules in biological samples for various research applications.
Why use a light microscope instead of a electron microscope?
A light microscope is suitable for observing living specimens and provides a lower resolution but a larger field of view, making it easier to study biological processes in real-time. In contrast, an electron microscope offers higher resolution and magnification, allowing for detailed examination of cell structures and organelles, but is typically used for non-living specimens due to the sample preparation techniques involved.
A bright field microscope can be used to view?
A bright field microscope can be used to view stained samples that absorb light, making them appear darker against a bright background. It is commonly used in biology labs to view cells, bacteria, and tissue samples.
What is properties of image observed under dissecting microscope?
Under a dissecting microscope, images appear three-dimensional and have a lower magnification compared to a compound microscope. The depth of field is greater, allowing for easier manipulation of specimens. Additionally, the lighting is usually brighter and can be adjusted to illuminate the specimen from different angles.
What are the characteristic of bright field microscope?
A bright field microscope is a type of light microscope that uses light from below the specimen to illuminate and create contrast with the specimen. It produces a dark image of the specimen against a bright background. Bright field microscopes are commonly used in biology labs for observing stained or naturally pigmented specimens.
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.

Which objectives of microscope covers a wider field?
Low power objectives cover a wide field of view and they are useful for examining large specimens or surveying many smaller specimens. This objective is useful for aligning the microscope. The power for the low objective is 10X.
Who invented the bright field microscope?
The bright field microscope was invented by Dutch scientist Antonie van Leeuwenhoek in the 17th century. He is known as the "Father of Microbiology" for his contributions to the development of the microscope and his observations of microorganisms.
How does a phase-contrast microscope differ from a bright field microscope?
1.diffrent typeof diaphraghms 2.a phase plate 3.living sample can be viewed 4.natural processes ccan be viewed without staining 5.enhances clarity 6.can be of two types :positive and negative positive:background much brighter than specimen negative:background is darker
When did frits zernike ivent the phase-contrast microscope?
Frits Zernike invented the phase-contrast microscope in the 1930s, and he was awarded the Nobel Prize in Physics in 1953 for his contribution. This type of microscope allows for the visualization of transparent specimens that would normally be difficult to see using traditional bright-field microscopy techniques.

A bright field microscope can be used to view stained samples that absorb light, making them appear darker against a bright background. It is commonly used in biology labs to view cells, bacteria, and tissue samples.
What microscope shows cells against a bright background and also shows intracellular structures of unstained cells based on their varying densities?
bright-field
How is brightfield used?
Brightfield microscopy is a common technique where light passes directly through a specimen, illuminating it and creating a bright background. It is often used for observing stained samples with high contrast. Brightfield microscopy is widely employed in biology to visualize cellular structures and study tissue samples.
What do you call the microscope used to study large specimens?
The microscope used to study large specimens is called a stereomicroscope or a dissecting microscope. These microscopes have a lower magnification power compared to other types of microscopes, allowing for a larger field of view and depth of focus to study three-dimensional objects.
