From the stereo microscope to this new species is now used, Dan the microscope: digital microscope. The digital microscope, also known as video microscope or electronic microscope. The image shown on a computer or on a screen. Can take pictures or video, image, post-processing function. Widely used in industry, agriculture, forestry, medicine, health, geology, archaeology, biology and so on.
Optical microscope is simple in terms of optical, lighting, mechanical three parts, can be imaged in the field of vision.
The difference between them lies in the digital microscope to be able to use the traditional optical microscope and camera system, combined with the computer monitor or, so can objects will be measured amplification, and the optical microscope can only is the product of the objective and the eyepiece, so as to obtain the magnification of the object to be measured.
But now science and technology is more and more developed, people for the study of the microscope is also more sophisticated, technology is becoming mature. Now the optical microscope can also connect to the computer, the camera. So that it is also increasing the magnification. As a result of 2006, the industrial camera is widely used in the detection of the factory, which greatly improves the production efficiency of the production line. And thus greatly reduce the production of workers with eye fatigue.
How to calculate its magnification?
What is the target size? In fact, the diagonal size of CCD or COMS, we use CCD or COMS, 2/3, 1/2, 1/3, 1/4, inch, the specific size is as follows:
1 inch - target size for wide 12.7mm* high 9.6mm, diagonal 16mm.
2/3 inch - target size for wide 8.8mm* high 6.6mm, diagonal 11mm.
1/2 inch - target size for wide 6.4mm* high 4.8mm, diagonal 8mm.
1/3 inch - target size for wide 4.8mm* high 3.6mm, diagonal 6mm.
1/4 inch - target size for wide 3.2mm* high 2.4mm, diagonal 4mm.
The formula for calculating the magnification of the digital microscope is as follows:
The magnification of the objective lens is X (the diagonal /ccd or CMOS of the computer screen) = the total amplification factor.
