In the field of modern optical imaging, telecentric lenses, with their unique performance and characteristics, are key components in many high-precision imaging applications. The following are the characteristics of is telecentric lenses:

1, With a very small object telecentricity error. This means that no matter how the distance of the object from the lens changes, the size of the image basically remains constant, thus effectively eliminating the imaging size error caused by changes in object distance. This feature is an irreplaceable advantage in applications that require precise measurement of object size, such as industrial inspection, machine vision and other fields. In industrial inspection, telecentric lenses can accurately detect the size, shape and surface defects of parts to ensure the consistency and reliability of product quality. In machine vision systems, it can accurately identify and locate objects, providing critical information support for automated production processes.

2, It is characterized by high resolution. It is able to capture the fine details of an object, providing clear, sharp images that help to detect minute defects or features, which are critical for quality control and precision manufacturing, among other things. For example, in semiconductor manufacturing, telecentric lens can clearly present the tiny lines and structures on the chip, to protect the high performance and stability of the chip.

3, Low distortion characteristics is also one of its significant advantages. In the imaging process, it can minimize the distortion and deformation of the image, making the resulting image more realistic and accurate reflection of the actual shape of the object. This feature has important applications in the field of medical imaging, such as in the observation of pathological sections, can provide doctors with accurate images to assist in the diagnosis of disease and research.

4, The depth of field is usually large. This makes in a certain range of object distance, the whole object can maintain clear imaging, without frequent adjustment of focus, improving the efficiency and stability of imaging. In such as three-dimensional measurement and reverse engineering, telecentric lenses can one-time access to the object of multiple levels of clear images, greatly improving work efficiency.

5, Good light uniformity. Can provide relatively uniform lighting effect in the entire imaging area, avoiding the image quality degradation caused by uneven lighting, providing better conditions for subsequent image processing and analysis. In scientific research, such as material analysis and biological experiments, telecentric lenses can provide high-quality, consistent imaging effects to ensure the accuracy and reliability of research results.

Telecentric lenses play an important role in industrial automation, medical imaging, scientific research and many other fields by virtue of their features such as small object-orientation telecentricity error, high resolution, low aberration, large depth of field and good light uniformity, providing reliable technical support for the realization of high-precision, high-quality optical imaging.
