Lenses for industrial digital cameras that are often used in industrial production include industrial telecentric lenses and ordinary industrial lenses. Because these two lenses are some distance away from our lives, many people do not understand the difference between these two lenses. What is the difference between telecentric industrial lens and ordinary industrial lens? Today Lingyun Editor will introduce you to the difference between the two industrial digital camera lenses to increase your knowledge reserve and satisfy your curiosity.
The main difference between the ordinary industrial lens and the telecentric industrial lens is that the ordinary lens is only a general lens and has the same function as other camera lenses. However, the telecentric lens adopts parallel optical path design, which can correct parallax of ordinary industrial digital camera lens. That is, the telecentric lens can be within a certain distance range, so that two objects will not be near and far away, so that the best photographic effect can be achieved. When using the ordinary industrial lens, the distance between the measured object and the lens is inconsistent and it is easy to form parallax. The data and images obtained are relatively unreal and cannot achieve the desired effect. Therefore, many industrial digital cameras will use telecentric lenses for imaging activities.
In addition, ordinary industrial digital cameras have many other disadvantages, such as severe lens distortion, low lens resolution, and uncertainty in the position of the edge of the image. In order to solve these shortcomings of ordinary lenses, competent scientific researchers have produced telecentric lenses, capable of effectively solving the shortcomings of ordinary industrial lenses. Therefore, the use of telecentric lenses can improve measurement and measurement. It has exceptional image quality and low distortion. Its characteristics are very suitable for the application of dimensional measurement and precision measurement. The comparison of the two objectives of
There is also a big difference between the telecentric lens and ordinary industrial lens shooting equipment. As we all know, ordinary industrial lenses do not use a flat design, which is very prone to visual errors. The round holes in the gear are visible in the photos taken, causing great difficulty for personnel viewing the photos. Compared with ordinary lenses, the optical path of the telecentric lens is a parallel light design. The images it takes are clearer and the data more real. It does not require personnel to perform image correction. In order to reduce the workload of staff, when using industrial digital cameras in many factories,
In short, when factories use industrial digital camera lenses, they can choose a suitable lens based on their actual situation. If the requirements of the factory & for pictures are not high, ordinary industrial lenses can be selected. However, when high measure images are required, it is better to choose a telecentric lens to get clearer image data.
