Actual magnification of the digital microscope
What is the magnification of the digital microscope ? This problem may not be clear to many users. Many friends want to know what the magnification is? Let me give you a brief explanation below, I hope to help everyone.
We use a formula to express: the magnification of the objective lens* (diagonal of the computer screen / ccd or the target size of cmos) = the magnification of the system.
The magnification of the objective lens: according to which magnification lens you are using, there are 5, 10, 20, 40, 60, 80, 100 and so on.
Note that the computer screen is usually expressed in inches, so multiply it by 25.4 millimeters. The diagonal of the computer screen: generally the unit is inches, for example, 14 inches should be multiplied by 25.4, the unit is mm; 1 inch = 25.4mm.
Target size of ccd or cmos: Commonly used CCD or COMS are 1, 2/3, 1/2, 1/3, 1/4 inch. Conventional digital microscopes are implemented using a third eye plus CCD or CMOS. If you have already purchased a traditional 2-purpose stereo, biological, and gold microscope, how can it be achieved? We will not eliminate the original purchased products, but also save costs and realize digital. We will directly observe the products on the computer screen and protect our eyes. It will be realized through transformation . (Guangzhou Mingmei has strong microscope technology transformation ability, so far Many universities and research institutes have also modified many microscopes and have rich experience in microscope reconstruction. Waiting for this magnification is closely related to the target size of CCD or COMS. Its size is directly related to the multiple of digital microscope.
So let's see what the target size is. In fact, it is the diagonal size of CCD or COMS. Our commonly used CCD or COMS has 1, 2/3, 1/2, 1/3, 1/4 inch. The specific dimensions are as follows:
1 inch - the target size is 12.7 mm wide by 9.6 mm high and 16 mm diagonal.
2/3 inch - the target size is 8.8 mm wide by 6.6 mm high and 11 mm diagonal.
1/2 inch - the target size is 6.4 mm wide by 4.8 mm high and 8 mm diagonal.
1/3 inch - the target size is 4.8 mm wide by 3.6 mm high and 6 mm diagonal.
1/4 inch - the target size is 3.2 mm wide by 2.4 mm high and 4 mm diagonal.
So we know the target size of the CCD or CMOS, and now it's easy to know what your digital microscope magnification is. According to our formula for digital magnification:
Magnification of the objective lens* (diagonal of computer screen / ccd or target size of cmos) = total magnification.
For example: 10x objective lens plus 1/3 inch CCD or CMOS digital microscope total magnification = objective lens 10 times * (15 inches * 25.4 / target size 6mm) = 635 times
