A telecentric industrial lens is a high-quality optical lens with high resolution and low distortion, which can correct the parallax of traditional lenses. The telecentric lens can reduce or even eliminate the magnification change, image distortion, perspective error, Problems such as poor image resolution are a key component in high-precision measurement vision systems.

 

Telecentric lenses can be divided into two types, one is a non-coaxial telecentric lens, the other is a coaxial telecentric lens, and a coaxial optical lens is a lens that uses coaxial epi-light illumination technology. More uniform lighting can detect the defects of objects more clearly, the image is clearer, the picture is more uniform, and the accuracy of the machine vision system is improved.

 

 

Advantages of coaxial optical telecentric lenses:

 


1. The use of infinite parallel light incident can achieve shadow-free lighting;

 

 

2. Uniform lighting ensures better magnification;

 

 

3. Coaxial lighting can effectively improve picture clarity.

 


The coaxial optical telecentric lens is suitable for the fields of semiconductors, electronic equipment, microelectronics and other microscopic objects with reflective properties that can only be observed under coaxial illumination. The characteristics of the coaxial phototelecentric lens can identify the characteristics of integrated circuits, glass, liquid crystal panels, etc., and are suitable for automatic imaging control of modern electronic manufacturing equipment.

 

 

There are a variety of magnification options for Pomeas telecentric lenses, and the production quality is strictly controlled, and the distortion rate is lower, which can better meet the requirements of machine vision system customers for optical lenses. Pumis also provides 4K zoom lenses, fixed focus industrial lenses and other products, which can meet more applications in modern industrial production.
