How To Choose The Lens Of An Industrial Camera?

Industrial cameras are also commonly known as cameras. Compared with ordinary cameras, industrial cameras have high image stability, high transmission capacity and high anti-interference ability. The performance of industrial cameras is stable and reliable, easy to install, compact and strong, not easy to damage, continuous operation It takes a long time and can be used in a poor environment, so how should I choose the lens of an industrial camera?

1. Do you need to use a telecentric lens:

For precision measurement systems, a telecentric lens is required. The main function of the telecentric lens is to overcome the effect of perspective phase difference (the phenomenon of inconsistent magnification due to different distances during imaging), so that the size data obtained when the detection target moves within a certain range is almost unchanged. In general, telecentric lenses have a fixed focal length and working distance, and some telecentric lenses are very large, and some weigh more than ten kilograms. It is necessary to understand the customer’s field of view size, working distance, space restrictions, and The requirements of motion control can only determine the required lens model specifications. When there are no strict requirements on the image of the object in general surface defect detection and judgment, choose a telecentric lens with small distortion.

2. Appearance function:

Most of the lenses of industrial cameras are designed with a waterproof body, so that they can be installed indoors and outdoors, avoiding installation waterproof problems.

3. Night vision clarity:

Industrial cameras are used in different installation environments, such as factory workshops, parks, traffic intersections, etc., to prevent people from theft and protect people’s lives and properties, especially in the dark and late night unattended, so the configured lens, its night vision Clarity is one of the important considerations.

The selection method of industrial camera will share the contents of the above three points for you today. In general, when choosing an industrial camera lens, the network digital camera is the first choice. To be more specific, we can choose according to the pixel, focal length, and installation environment. And so on to choose.
