Advantages and disadvantages of industrial telecentric lenses




In machine vision inspection, it is necessary to use a lens for image shooting. The traditional industrial lens is the same as the human eye. Due to the angle of view, there is a phenomenon of "closer and far smaller" when viewing objects. If such a lens is used in the measurement system The object distance often changes, so that the image height changes, so the measured object size also changes, that is, a measurement error occurs; on the other hand, even if the object distance is fixed, it will be difficult because the CCD sensitive surface is not accurate. Adjustment on the image plane will also produce measurement errors.


The industrial telecentric lens can effectively solve the above problems. The image-side telecentric lens can eliminate the measurement error caused by the change of the object distance, and the object-side telecentric lens can eliminate the measurement error caused by the inaccurate CCD position. 



The industrial telecentric lens has the advantages of ultra-wide depth of field and low distortion, and the magnification does not change with depth, which can eliminate the worry of measurement errors in precision measurement applications. And with unique optical design, high resolution, ultra-wide depth of field and other advantages, it can be used in precise dimension measurement, micro-etching, semiconductor inspection and other scenarios, making machine vision technology effectively improved.



Pomeas telecentric lens has high resolution, low distortion rate, and various types, which can better meet the requirements of machine vision customers for industrial lenses and provide customers with more complete solutions.
