The English name of optical zoom is OpticalZoom, and digital video cameras rely on the structure of optical lenses to achieve zooming. Optical lens is an essential part of machine vision system, which directly affects the quality of imaging, and affects the realization and effect of algorithms.....

The aperture of the lens is mainly used to adjust the size of the aperture or opening of the lens, so as to control the amount of light entering the lens, so that the image can be correctly exposed. In this way, the image will not be too bright in a well-lit scene, and at the same time, the image will not be too dark in a dark environment. On the other hand, the size of the aperture will also affect the depth of field of the image. The smaller the aperture, the longer the depth of field. The larger the aperture, the shorter the depth of field. Long depth of field is particularly important in some surveillance scenarios, such as narrow passages or parking lots. Conventional lens aperture control methods are mainly fixed aperture, manual aperture, automatic aperture and electric aperture....

Back Focus Adjustment/Back Focus Adjustment Back Focus Adjustment means adjusting the flange distance (the distance from the lens interface surface to the imaging chip) to 17.526mm, which is the standard C-mount...

With the development of science and technology, the application of industrial cameras and machine vision is becoming more and more extensive. Commonly used industrial camera lens interfaces include C interface, CS interface, F interface, M42 interface, M72 interface, etc. F-mount, M42, M72 are commonly used in large-resolution area scan cameras and line scan cameras. Today I will mainly introduce the most commonly used C-mount and CS-mount. The difference in the type of the interface is not directly related to the performance and quality of the industrial lens. The reason for these two types of mounts is because of different standards. Do companies sell standards"?

Electric motors are an important part of industrial production. With different application scenarios, there are many different types of motors, which can be selected according to operation, voltage and application conditions. Motor devices can be found in applications ranging from video cameras to fans to DVD players. Selecting the right motor for a project has become more difficult in recent decades as motor technology has advanced and there are so many variables to consider. This article aims to help you understand the difference between stepper motors and DC motors.
