The advantages of dual telecentric lenses

            The advantages of dual telecentric lenses: zero distortion, no perspective error, especially suitable for high-precision detection and measurement industry applications; The disadvantage is that it has higher costs.

           In the industry application of machine vision technology, telecentric lens technology plays an indispensable role and has become a decisive component of precision optical measurement systems. The new dual telecentric industrial lens series products are object/image dual telecentric lenses developed based on the extensive on-site needs of users. This lens is a key component of various precision measurement systems based on machine vision technology, with almost no distortion in imaging. Not only can it enhance the natural depth of field by utilizing aperture and magnification, but it also has unparalleled optical effects compared to non telephoto lenses.

           Throughout the development of the industry, with the increasing demand for high-precision detection and measurement applications, the application of high-performance machine vision dual telecentric optical detection systems and equipment will also be further enhanced. Machine vision inspection equipment based on dual telecentric optical systems, driven by market demand for visual inspection, has been successfully put into industrial applications, solving a type of dimensional inspection problem in industrial manufacturing processes and providing an efficient inspection method for the industrial manufacturing industry. Greatly improve the quality and performance of precision products, shorten the testing cycle, and reduce labor costs.

              Machine vision inspection equipment based on dual telecentric optical system is suitable for industrial applications 

              With the rapid development of automated detection technology, the industry's demand for high-precision detection and measurement is gradually increasing. Traditional technical solutions are no longer sufficient, so the application of machine vision detection systems and equipment is not improving. Machine detection equipment based on dual telecentric optical systems has performance advantages such as no perspective error, almost zero distortion, and high resolution, making it fully compatible with industrial applications and the best solution for high-precision detection.

              As a major pillar of machine vision applications, optical systems are an indispensable technology, and the advantages of telecentric optical systems in industry applications are already evident. The so-called telecentric optical system refers to an optical system in which the principal ray is parallel to the optical axis of the lens. And when light is emitted from an object towards the lens, kept parallel to the optical axis, and even outside the axis, it is called an object side telecentric optical system; When light is directed from the lens towards the image and remains parallel to the optical axis, even outside the axis, it is called an image side telecentric optical system.

              When it comes to telecentric optical systems, we cannot ignore the telecentric lens. A telecentric lens is a high-end machine vision lens and the core component of a telecentric optical system. It can usually be divided into two categories: object side telecentric lenses and dual telecentric lenses.

             The advantage of the object side telecentric lens is that it does not change the size or position of the object when moving the surface up and down. When using coaxial lighting. Smaller sizes can be used.
