The Sensor size of an industrial lens is the diagonal length of the CMOS image sensor (Sensor) in the camera module in inches. For historical reasons, in the field of electronic component imaging, 1 inch in Sensor size is equal to 16mm instead of the conventional 25.4mm.Common Sensor sizes are 1/4'', 1/3'', 1/2'', 2/3'', 1'', and so on.

There are several factors to consider when choosing the Sensor size for your industrial lens:

1, resolution requirements: according to the application requirements to choose the appropriate resolution, the higher the resolution, the higher the number of pixels in the image after imaging, the clearer the image. However, high resolution will also bring a larger amount of data, increasing the complexity of the later algorithm processing. Therefore, when choosing the Sensor size, you need to weigh the resolution and data processing capacity according to the actual needs of the project.

2, the camera and the lens match: the target surface size of the lens (that is, the lens can support the largest CCD size) should be greater than or equal to the size of the optional camera CCD chip. If the lens target size is smaller than the camera CCD chip size, there will be a blurred image edges or black edges and other issues. Therefore, in the selection of industrial lenses, you need to ensure that the target size of the lens and the camera CCD chip size match.

3, working distance and angle of view: focal length is another important factor to consider when choosing industrial lenses. The larger the focal length, the larger the working distance, the smaller the angle of view; the smaller the focal length, the smaller the working distance, the larger the angle of view. Therefore, when choosing industrial lenses, you need to choose the appropriate focal length according to the actual working distance and viewing angle needs.

4, sensor size: the larger the sensor size, to a certain extent, that the camera can accommodate more pixels, the larger the imaging frame. However, a large sensor size will also bring the problem of increased lens costs.

Selecting the Sensor size of an industrial lens requires consideration of factors such as resolution requirements, camera and lens matching, working distance and angle of view, and sensor. In practical applications, it is also necessary to consider these factors according to the specific needs and scenarios to choose the most appropriate industrial lens.
