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

2026-08-14

Why do industrial cameras need to add lenses? The function of industrial lenses is optical imaging. Industrial lens is an important component in the machine vision system and plays a key role in imaging quality. It affects several of the most important 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.

So, how should you choose the lens of an industrial camera? The following points should be paid attention to.

Wavelength, zoom or not. The working wavelength of the industrial camera lens and whether it is needed;
Special requirements may be given priority based on actual application characteristics;
Working distance and focal length Working distance and focal length are often considered together;
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;
Aperture and interface; the aperture of the industrial camera lens mainly affects the brightness of the image surface;
