The Difference Between a Metallographic Microscope and an Optical Microscope
Microscopes help users observe life, but life contains many samples with different structures, such as birds, animals, soil, sand, and stones. Therefore, when observing different samples, we need to apply different tools. So, what is the difference between metallographic microscope and optical microscope?
Microscopes can generally be classified according to their applications and structures, including biological microscopes, polarizing microscopes, and metallographic microscopes. The metallographic microscope we refer to is actually a branch of the microscope, which is used to observe and study the metallographic structure of certain samples in the industrial field.
In fact, ultimately, metallographic microscopes belong to optical microscopes. Metallographic microscopes are essential accessories and functions added to optical microscopes for industrial research, such as bright and dark field observation, polarization observation, and differential interference observation. Metallographic microscopes are generally used as microscopes for metallographic testing.
The above is an introduction to the differences between metallographic microscopes and optical microscopes. In fact, there are no similarities or differences in the overall structural types of various microscopes. It is only necessary to modify the microscope appropriately according to different application requirements to meet the corresponding research needs. That's all.
What is the maximum magnification of an optical microscope?
The magnification of an optical microscope is limited by the magnification of the objective lens, up to a maximum of 1500 times!
Under normal circumstances, the objective lens group has 4 lenses with magnifications of 4, 10, 40, and 100 times each, and the eyepiece lens group has 3 lenses with magnifications of 5, 10, and 15 times each. The total magnification of the microscope is equal to the objective lens magnification multiplied by the eyepiece magnification, with 100 * 15=1500 times.
No matter how large it is, it only increases the magnification of the eyepiece, but there will be no further details, which is considered ineffective magnification. It's like looking at a photo with a magnifying glass (the image of the objective lens), no matter how large the magnification is, you can't see the image that the photo itself didn't capture. This is limited by the principle of optical microscopes. In order to achieve higher magnification, other structures of microscopes such as electron microscopes can be used, which can achieve 1000 times the theoretical value of optical microscopes.
