"5MP Industrial Camera" Why do industrial cameras need to add lenses?

Industrial cameras are also commonly known as video cameras. Compared with traditional civilian cameras (video cameras), they have high image stability, high transmission capabilities and high anti-interference capabilities. Most of the industrial cameras on the market are based on CCD or CMOS chip cameras. Anyone who knows something about industrial cameras knows that many industrial cameras will have a lens added to them. So, why do industrial cameras need to add lenses? Let’s learn about it with the editor of Dior Technology, an industrial camera manufacturer!

The function of industrial lenses is optical imaging. Industrial lenses are important components in machine vision systems and play a key role in imaging quality. They have an impact on several major indicators of imaging quality, including: resolution, contrast, depth of field and various aberrations. Moreover, there are not only many types of industrial lenses, but also very different quality. However, ordinary users often do not pay enough attention to industrial lenses when designing machine vision systems, resulting in failure to obtain ideal images and even system development failure. Therefore, it is very necessary to add a good lens to the industrial camera.

1. Wavelength, zoom or not. The working wavelength of the industrial camera lens and whether it is needed;
2. Special requirements may be given priority based on actual application characteristics;
3. Working distance and focal length Working distance and focal length are often considered together;
4. Image surface size and image quality; the image surface size of the selected industrial camera lens must be compatible with the size of the camera's photosensitive surface; the image quality requirements mainly focus on MTF and distortion;
5. Aperture and interface; the aperture of the industrial camera lens mainly affects the brightness of the image surface;
