Scientific research CCD selection in the field of microscopic imaging

The role of scientific research CCD in microscope application is to take clear and accurate images of the images observed under the microscope, and at the same time, through the transmission, the images are quickly output to the image processing software to ensure that the images can be used for analysis and detection. The ability to capture images clearly and accurately is critical to the entire process, and the decision-making CCD is scientific. At the same time, factors that determine whether the CCD meets the requirements of the microscope application include clarity, illumination, distortion, etc. Below, a few factors are selected for simple analysis.

● clarity. As long as it involves the collection of images, clarity is one of the factors that must be considered. To determine whether a scientific-grade CCD can meet the microscope application, it is necessary to use a special test card to measure while maintaining the lens unchanged. The measurement content includes the vertical and horizontal definition of the CCD. During the test, the focus can be focused, or the side of the test can be focused to analyze the CCD.

● Sensitivity. Sensitivity is an important feature of CCD and a key factor in determining whether a clear image can be obtained in the background. Observe an object from a distance and observe the presence of color distortion. When compared with other objects with bright colors, you can quickly determine the sensitivity of the scientific CCD. In addition, in addition to long-distance observation, it is also necessary to perform close-range testing. For example, a color picture book can be placed in front of the CCD to observe the sharpness and color distortion of the picture.

● Illumination. In general, environmental factors in microscope applications are also important, so illuminance is also a point of testing scientific CCD. We often use the CCD in the dark room, the 220V incandescent lamp is placed in front of and behind the darkroom. By adjusting the indoor illumination, the illuminance value of the CCD is observed to determine whether the microscopic demand is met.

● Distortion. The main point here is to detect the spherical distortion of the scientific CCD. Place the test card with the sphere on the front end of the CCD so that the whole sphere can appear on the screen completely to see if the circle is oval. Then move the CCD forward and see if there is any enlargement in the center of the circle. Pull the CCD far away and see if the edges, corners, and frames have arc distortion.

The above are just a few conventional methods of judging. In actual operation, there may be more constraints. The effect of importing scientific research CCD is very good. The price is there. Tucson is relatively late in this field compared with foreign manufacturers. However, Tucson has developed very well in recent years, insisting on independent research and development, technological innovation, and all aspects have gradually approached the international advanced level. The first-class quality, the price of the people, and the perfect after-sales allow Tucson to be in the domestic research-grade CCD. With good reputation, Tucson launched a new 2.8 million scientific and technological black-and-white semiconductor refrigeration CCD in 2013. The cold CCD camera adopts Sony's top ICX674AL chip, which is designed for low-light imaging users to design semiconductor refrigeration technology and multiple noise reduction technologies. . Semiconductor refrigeration technology can greatly reduce the noise of long time taking pictures. At the same time, the unique anti-glow technology reduces the glow of the chip during long exposure, which makes the image achieve a good linear effect. In addition, in terms of software, we have built hardware integration, irregular scores and other user-friendly settings for low-light shooting, making the user more friendly and user-friendly in terms of testing and control. For instrument developers, the SDK is provided to assist users in development, and our control interface can be changed as needed to save end-user development time and facilitate product integration.
