In fact, the gel imaging produced by each company is similar in structure, and can be used for non-chemical luminescence such as DNA/RNA/protein gel electrophoresis (such as EB, Coomassie blue, silver staining). Imaging detection analysis mainly distinguishes the sensitivity and resolution of gel imaging. The quality of the image to be photographed depends mainly on the size of the CCD, the pixel, and a software function of imaging.
Gel imaging CCD structure decomposition - Shanghai Peiqing gel imaging manufacturers in detail for you to answer:
The first layer of "enhanced lens" We know that the key to digital camera imaging lies in its photosensitive layer. In order to expand the CCD's luminous rate, it is necessary to extend the light receiving area of ​​a single pixel. However, the method of increasing the daylighting rate is also likely to degrade the image quality. This layer of "micro lens" is equivalent to adding a pair of glasses in front of the photosensitive layer. Therefore, the photosensitive area is no longer determined by the opening area of ​​the sensor, but is determined by the surface area of ​​the microlens.
The second layer is the “separation filterâ€. The second layer of the CCD is the “separation filterâ€. There are currently two color separation methods, one is the RGB primary color separation method, and the other is the CMYK complementary color separation method. Both methods have their own advantages and disadvantages. First of all, let us first understand the concept of two color separation methods, RGB is the three primary color separation method, almost all the colors that human glasses can recognize, can be composed of red, green and blue, and the three letters of RGB are Red. Green and Blue, which means that the RGB color separation method is adjusted by the color of these three channels. Let's talk about CMYK, which is made up of the colors of four channels. They are cyan (C), magenta (M), yellow (Y), and black (K). In the printing industry, CMYK is more suitable, but its adjusted color is not as much as RGB. The advantage of the primary color CCD is that the picture quality is sharp and the color is real, but the disadvantage is the noise problem.
Therefore, you can note that digital cameras that use primary color CCDs generally do not exceed 400 in ISO sensitivity. In contrast, the complementary color CCD has a Y yellow color filter, which is more careful in color resolution, but sacrifices the resolution of some images. In the ISO value, the complementary color CCD can tolerate higher sensitivity, generally The third layer can be set above 800: the third layer of the photosensitive layer CCD is the “photosensitive sheetâ€, which is mainly responsible for converting the light source that passes through the filter color layer into an electronic signal and transmitting the signal to the image processing system of the gel imaging system. Chip, restore the image. The conventional camera film size is 35mm, 35mm is the diagonal length, and the 35mm film has a photosensitive area of ​​36 x 24mm. Converted to a digital camera, the diagonal length is approximately 35mm, and the CCD/CMOS size is larger. In SLR digital cameras, many have CCD/CMOS sizes close to 35mm, such as the Nikon D100. The CCD/CMOS size is 23.7 x 15.6, which is much larger than the consumer digital camera, and Canon's EOS-1Ds CMOS. The size is 36 x 24mm, which is 35mm, so the imaging is relatively good.
