CCD Interface Introduction of Microscope
The microscope interface is a necessary device to connect the microscope and digital equipment. It not only plays a connection role, but also plays a vital role in displaying the images formed by the microscope on the monitor. Since optical imaging is a very complicated process, the digital interface has a great influence on light compensation, transmittance, dispersion, balance, strength, etc., and plays a great role in image correction and compensation. Therefore, the analysis of the real image by the digital microscope interface is also an important link.
In addition to the common 1X interface, the C-type interface adapter of the microscope also has two options: 0.5X and 0.63X. The choice of the adapter is related to an important parameter of the Olympus microscope - the field number. The field number (FN) is the diameter (mm) of the field of view that can be observed through the eyepiece. The diameter of the circular area where the specimen can actually be observed under the microscope is called the object field of view. The field of view of the object side = the number of fields of view/magnification of the objective lens. Since the diameter of the human eye is about one inch (25.4mm), the field numbers of the eyepieces are 18, 20, 22, 26.5, etc. However, since the commonly used camera chips are generally 1/3 inch and 1/2 inch in size, their field of view is relatively small compared to eyepiece observation. This also led to the fact that the amount of information collected by the camera is relatively small when the customer uses the 1X interface to connect the camera. To solve this problem, we recommend customers to use 0.5X and 0.63X Olympus microscope C-mount. Through the 0.5X interface, the image captured by the camera is reduced by 1/2, which is equivalent to 1 inch*0.5 = 1/2 inch. In this case, the size of the image captured by the 1/2-inch chip's camera is similar to that seen in the eyepiece.
