In the fast-growing smartphone manufacturing industry, ensuring that the screen size of cell phones is accurate and precise is a key part of improving product quality and meeting market demand. Traditional size inspection methods often suffer from inefficiency, lack of precision or the need for multiple measurements, while the introduction of dual telecentric lenses provides an innovative solution to this challenge.

The dual telecentric lens, as an advanced optical imaging system, is unique in its dual-port design, which is able to simultaneously support two cameras working at different magnifications. This feature makes it flexible in the face of complex and changing inspection tasks, especially in the need to observe a wide range of details and local fine structure at the same time in the scene with excellent performance. In cell phone screen size inspection, the dual telecentric lenses are able to simultaneously display two magnifications of 0.16X and 0.7X, realizing comprehensive coverage from macro to micro.

Applications:

Efficient one-time inspection: While traditional methods may require multiple adjustments to the lens or camera position to obtain dimensional data for different areas, the dual telecentric lens is able to complete the inspection of the entire cell phone screen size at one time. Through its dual-port design, the low-magnification (e.g., 0.16X) camera is used to quickly capture the overall contour of the phone screen to ensure that the dimensions roughly meet the design requirements; meanwhile, the high-magnification (e.g., 0.7X) camera focuses on fine measurements of the screen's edges, corners and other key areas to ensure that the dimensional accuracy reaches the micron level.

Enhance inspection accuracy: The telecentric design of the dual telecentric lenses effectively eliminates image distortion caused by changes in object distance and ensures that images acquired at different magnifications have extremely high geometric accuracy. This is crucial for components such as cell phone screens, which require extremely high dimensional accuracy, and helps manufacturers strictly control product quality.

Automation and Intelligent Integration: Combined with advanced machine vision algorithms and automation control system, the dual telecentric lens inspection system is able to realize fully automated operation, reduce manual intervention, and improve inspection efficiency and accuracy. At the same time, through data analysis and feedback mechanisms, the system can also continuously optimize the inspection process to further improve production efficiency and product quality.
