What is the relationship between the diameter of the microscope field and its magnification?
The field of vision shrinks as the magnification gets higher so as the magnification increases the less of the diameter of the microscopic field you can see.
What happens to the depth of field as the magnification increases?
As the magnification increases, the depth of field decreases.
What microscope is the least powerful?
Short Answer: The unaided human eye which has a magnification of 1X and can resolve details down to about 0.2 millimeters. Longer Answer: Depending on the type of lens a single lens magnifier can magnify up to about 12X and resolve down to 17 micrometers. A multiple lens achromatic magnifier can go up to about 25X and resolves down to about 8 micrometers. Stereo microscopes that can easily view 3-D objects go up to about 1000X and resolve down to about 150 nanometers. Likewise, any optical microscope is limited by the diffraction limit of light to about 1300X of usable magnification. More magnification will just produce a larger version of the image that is blurry since it is not possible to sharpen the focus beyond the 150 nanometer diffraction limit. Microscopes that use ultraviolet light, which has a shorter wavelength that can focus tighter, can resolve down to 10s of nanometers or about 10 times better than visible light microscopes for a magnification of 10,000 X. Modern Scanning Electron Microscopes (SEM) are capable of resolving down to about 0.2 nanometers which translates to a useful magnification of 1,000,000 X. Specialized types of electron microscopes (Field Emission Transmission Electron Microscopes) can resolve down to 0.05 nanometers which translates to a magnification of 2,500,000 X. For reference, a carbon atom is about 15 nanometers in diameter.
What does it mean for a microscope to be parcentered?
When a microscope is parcentered, the specimens will appear centered in the field of view at every magnification. So if a field of a slide is centered at the lowest power, even though the field diameter shrinks at each higher magnification, the desired part of the specimen will remain in the center of the viewing field.
What happens to the field of view in a microscope when the total magnification is increased?
it becomes bigger
What is the relationship between the size of the field of view and the magnification?
As you increase the magnification, the field of view decreases.
What is the relationship between the size of the field of view and magnification?
As you increase the magnification, the field of view decreases.
What is the relationship between magnification and the diameter of the field of view?
Magnification is inversely proportional to the diameter of the field of view.
What is the relationship between the diameter of the microscope field and its magnification?
The field of vision shrinks as the magnification gets higher so as the magnification increases the less of the diameter of the microscopic field you can see.
What are the similarities between the microscopes made by Anton van Leeuwenhoek and the microscopes used nowadays?
both are bright field microscopes, and works on two lenses
What happend to the depth of field if magnification increases?
The higher the magnification the lower the depth of field.
What happens to the depth of field as the magnification increases?
As the magnification increases, the depth of field decreases.
Microscopic field size increase with higher magnification?
Magnification is related because as magnification increases, the depth of field decreases.
How are microscopes used today?
microscopes are used in labs, medical field, surgeries, astronomy and crime investigation field
What happens to the field of view in a compound in a compound light microscope when the total magnification is increased?
The field of view becomes smaller when magnification increases.
What is the relationship between the size of the field of view from a microscope and the objective used to observe the field?
As the magnification of the objective increases, the FOV decreases
Is Bright-field microscopes are used for most microscopic work?
Bright field microscopes are most used for microscopic work.
