How is a microscope's magnification determined?
Many laboratories are using microscopes, but they don’t know the relevant professional knowledge of microscopes. They just know how to operate them, but they may not be very clear about some basic common sense. So today we will talk about the magnification of microscopes. computational?
Some people may say that this is not a very simple problem, but it is actually a little complicated.
First of all, let's give an example: when the magnification of the stereo microscope eyepiece is 10 times, the zoom range of the zoom body is: 0.7X-4.5X, and the additional objective lens is: 2X. Then its optical magnification is: 10 times 0.7 times 2 to get the minimum magnification of this microscope: 14 times, then the maximum magnification is: 10 times 4.5 times 2 equals 90 times, then the optical total of this stereo microscope The magnification is 14 times to 90 times. Of course, this is only the actual magnification of the microscope host. Next is the microscope digital magnification.
For example, if the size of the display is 17 inches and a 1/3 microscope camera is used, then the digital magnification of the microscope camera compared to the table below is: 72 times. The calculation formula of the digital magnification of the microscope is: based on the configuration of the stereo microscope above, the zoom body is 0.7X-4.5X, and the additional objective lens is 2X. The camera eyepiece is 1 (if the camera eyepiece has no multiple, it does not need to be added to the calculation). According to the formula: objective lens X camera eyepiece magnification X digital magnification, the minimum magnification of digital magnification is: 0.7 times 2 times 1 times 72 is equal to: 100.8 times, the maximum magnification of digital magnification is: 4.5 times 2 times 1 times 72 is equal to: 648 Times. The digital magnification range is 100.8 times to 648 times.
In this case, two formulas will appear:
1. The total optical magnification = the magnification of the eyepiece X the magnification of the objective lens
2. Digital total magnification = objective lens X camera eyepiece magnification X digital magnification
This formula is suitable for any microscope, whether it is a metallographic microscope, a biological microscope, etc.
