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 else can I help you with?
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.
Can a bright field microscope be used to view living specimens?
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.
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.
What does microscope field mean in science?
In science, the term "microscope field" refers to the area or magnified region that is visible through a microscope lens at any given time. It represents the specific part of the sample or specimen that is being observed under the microscope. The size of the microscope field can vary depending on the magnification and the type of microscope being used.
Which characteristic of life is shown when you squint in bright light?
The characteristic of life demonstrated in squinting in bright light is response to stimuli. Squinting is a reflex action that helps protect the eyes from excessive light and is triggered by the sensory input of bright light.
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.

What microscope shows cells against a bright background and also shows intracellular structures of unstained cells based on their varying densities?
bright-field
The ordinary light microscope is called a bright-field microscope because?
the object appears light on a dark background
What are the part of a microscope?
First of all which microscope do you want to know the parts to? A scanning electron microscope? Transition electron microscope? Bright field? Dark field? Phase contrast? Confocal? These parts of found on a bright field light microscope: fine adjustment knob coarse adjustment knob slit light reflected mirror diaphragm objective lens handle stage clips nosepiece revolving nose piece Base arm eyepiece stage bodytube stage

What is Dark field microscope?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

A microscope used for viewing things through which light cannot pass is a?
A dark-field microscope. This type of microscope uses scattered light to enhance contrast and allow for the visualization of transparent or translucent samples that would be difficult to see using bright-field microscopy.
Is the depth of field on a dissecting microscope less than the depth of field on a compound microscope?
Yes, the depth of field on a dissecting microscope is greater than on a compound microscope. This is because the dissecting microscope has lower magnification, allowing for a wider field of view and greater depth perception.
What is a microscopic field?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'
