　　Calculation method for actual magnification of microscope
We all know that microscopes have magnification, which is calculated by multiplying the magnification of the eyepiece by the magnification of the objective lens. However, this is just a simple formula for calculating the magnification of the objective lens and eyepiece. With the continuous development of microscope technology, many microscopes are now implemented through CCD+computers. When we observe, we can directly observe through the computer screen. In this way, the actual magnification of the microscope is different because compared to observing through the eyepiece, the field of view does not change when observing through the computer screen, but the degree of magnification changes, that is, the actual magnification changes. Usually, we use a formula to express:
The magnification of the system is equal to the magnification of the objective lens multiplied by the diagonal of the computer screen or the size of the CMOS target surface
The magnification of the objective lens: conventional ones include 5, 10, 20, 40, 60, 80, and 100x
Computer screens are usually measured in inches, so they need to be multiplied by 25.4 millimeters to obtain units. The diagonal of a computer screen is usually measured in inches, for example, 17 inches should be multiplied by 25.4 in millimeters; 1 inch=25.4mm. The target size of CCD or CMOS: commonly used CCDs or COMS have 1, 2/3, 1/3, and 1/4 inches. Conventional digital microscopes use a third lens combined with CCD or CMOS to achieve this, and the target size directly affects the magnification of the digital microscope. In fact, the target size is the diagonal size of CCD or COMS. The commonly used CCD or COMS have 1, 2/3, 1/2, 1/3, and 1/4 inches. The specific sizes are as follows:
1 inch - The target surface size is 12.7mm wide by 9.6mm high, with a diagonal of 16mm.
1/2 inch - The target surface size is 6.4mm wide by 4.8mm high, with a diagonal of 8mm.
1/3 inch - The target surface size is 4.8mm wide by 3.6mm high, with a diagonal of 6mm.
1/4 inch - The target surface size is 3.2mm wide by 2.4mm high, with a diagonal of 4mm.
2/3 inch - The target surface size is 8.8mm wide by 6.6mm high, with a diagonal of 11mm.
So now that we know the target size of CCD or CMOS, it's easy to determine the magnification of your microscope. According to our formula for digital magnification, the magnification of the objective lens multiplied by (the diagonal of the computer screen/cd or the target size of the CMOS) equals the total magnification. For example, the total magnification of a digital microscope with a 10x objective lens and 1/3 inch CCD or CMOS=10x objective lens * (15 inches * 25.4/target size 6mm)=635 times.
