The emerging digital microscope, also known as video microscope, combines ordinary optical microscope with digital imaging system, so that the images observed in the microscope field of view are presented on the display with high resolution. Video microscopes have high imaging quality and can be used in many fields such as electronics, precision engineering, instrumentation, scientific research, etc. In order to buy a good quality video microscope, one should know clearly which hardware indicators can evaluate the performance of a video microscope.
Similar to digital camera, the imaging quality of video microscope is highly dependent on high quality chip. A high quality chip can provide fine details, true colors and low noise images, which also determines the magnification times. Therefore, when people evaluate the performance of video microscopes, they should pay attention to the chip pixel index, which is also an indicator that people should decide carefully when purchasing. Different from the magnification of traditional optical microscope, the magnification times of video microscope includes optical magnification times and digital magnification times. Optical magnification is consistent with the algorithm of ordinary optical microscope, which mainly determines the clarity of the image in the optical field of view. Digital magnification mainly refers to the resolution of the image presented in the video system.
Common are semiconductor processing and inspection and microelectronic assembly in industrial applications. With the improvement of modern process technology, the development trend of various components is gradually miniaturized and precision, so it is difficult to process inspection by human naked eye alone, video microscope can be very good to assist in observation for these fields of process. In the textile field, video microscope can be used for microscopic observation and analysis of textile materials, microscopic observation and analysis of shaped cross-sectional fiber characteristics, diameter testing of yarns, yarn structure analysis and other operations, with video microscopy of textile materials microscopic photography can be more convenient and rapid image recording of fibers, yarns and fabrics, monitoring the performance of fabric advantages and disadvantages.
The role of video microscopy in the field of biological research is irreplaceable, such as cell biology, embryo or sample cultivation and other research requires microscopy for real-time monitoring, video microscopy by detecting lesions skin cells peripheral and deep skin edge detection of residual basal cell carcinoma and squamous cell carcinoma, as well as the observation of normal skin nuclei and cell morphology characteristics can be evaluated in Mohs micrographic surgery of cancer margins.
In terms of education and teaching, the observation of the appearance of individual organisms or other tiny objects is an important practical part of the teaching content, such as the introduction of the morphological structure of grass worms and biological cells. In the limited course time, it is difficult to ensure that the teaching content of each student can be implemented in place, and the introduction of video microscopy overcomes the undesirable factors caused by the differences in students' operation levels, and can present the microscopic things through the screen to each The introduction of the video microscope overcomes the undesirable factors caused by the difference in students' operating levels, and can present microscopic things to each student through the screen, which is conducive to experimental demonstration and the improvement of students' overall cognition.
PCB circuit board, also known as printed circuit board, is an important part of electronic equipment. With the rapid development of the semiconductor industry, people's demand for pcb circuit board is more and more, the quality requirements are more stringent, so microscope can come in handy for pcb circuit board inspection, the circuit board is very large, the components are also very large, so we usually recommend customers to use small magnification, large depth of field, large field of view, and a large range of movement of the microscope. Generally speaking, whether it is binocular microscope or video microscope, such requirements can be achieved through the replacement of the stand and objective lens. Usually we will recommend monocular microscope+CCD+monitor to our customers, so binocular and trinocular stereoscopic microscopes are not recommended for the sake of efficiency.
In conclusion, wherever traditional microscope can be applied to the field, video microscope can also be competent, and even better in some aspects, confirming that video microscopy imaging technology is an effective imaging technology for observation of microscopic fields.
