In the integration of machine vision systems, industrial lenses are used. The imaging quality of different industrial lenses varies widely, even for industrial lenses of the same type. This is mainly due to factors such as material, processing accuracy, and lens structure. At the same time, the price of industrial lenses of different grades varies from hundreds to tens of thousands of yuan. Aberration is an important factor affecting the quality of machine vision inspection graphics. Common aberrations include spherical aberration, coma, astigmatism, field curvature, chromatic aberration, and distortion.

When evaluating the quality of industrial lenses, it is generally judged from several practical parameters such as resolution, sharpness, and depth of field: 1. Resolution refers to the ability of the lens to clearly distinguish the details of the subject. 2. Brightness, or contrast, refers to the contrast of the lightest and darkest parts of the image. 3. Depth of field. In the scene space, scenes located within a certain distance before and after the focus object plane can also form a relatively clear image.
