Teach you how to calculate the actual magnification of a microscope
Many customers call me and ask me what is the maximum magnification of a microscope. Let me give you a simple explanation. I hope it will be helpful to you. We use a formula to express: the magnification of the objective lens (the diagonal of the computer screen/the target surface size of CCD or cmos) = the magnification of the system. The magnification of the objective lens: The conventional ones are 5, 10, 20, 40, 60, 80, and 100x. You can also choose according to the needs of the customer.
Computer screens are generally expressed in inches, so multiply by 25.4 to get the unit of millimeters. The diagonal of a computer screen: Generally, the unit is inches. For example, if it is 17 inches, it should be multiplied by 25.4, and the unit is mm; 1 inch = 25.4mm.
Target surface size of CCD or CMOS: Commonly used CCD or COMS are 1, 2/3, 1/2, 1/3, and 1/4 inches. Conventional digital microscopes are implemented using a third eye plus CCD or CMOS. , then if you have purchased a traditional 2-purpose stereo, metallographic and other microscopes; how to achieve it? In order to not eliminate the original products purchased, but also to save costs and realize digitalization, directly use the computer screen to observe the products, and at the same time protect our eyes, this must be achieved through transformation. When the magnification is closely related to CCD or COMS The size of the target surface is directly related to the magnification of the digital microscope.
So let's take a look at what the target size is? In fact, it is the diagonal size of CCD or COMS. The commonly used CCD or COMS are 1, 2/3, 1/2, 1/3, and 1/4 inches. The specific sizes are as follows:
1 inch - target surface size is 12.7mm wide * 9.6mm high, diagonal 16mm.
1/2 inch - target surface size is 6.4mm wide * 4.8mm high, diagonal 8mm.
1/3 inch - target surface size is 4.8mm wide * 3.6mm high, diagonal 6mm.
1/4 inch - target surface size is 3.2mm wide * 2.4mm high, diagonal 4mm.
2/3 inch - target surface dimensions are 8.8mm wide*6.6mm high, diagonal 11mm.
So now that we know the target surface size of CCD or CMOS, it is easy to know what the magnification of your microscope is. According to our digital magnification formula:
Magnification of objective lens * (diagonal of computer screen/target surface size of CCD or CMOS) = total magnification.
For example: the total magnification of a 10x objective lens plus a 1/3-inch CCD or CMOS digital microscope = 10x objective lens * (15 inches * 25.4 / target surface size 6mm) = 635 times
