Quality inspection of screen screen printing is critical in the cell phone manufacturing process. Accurate, clear and efficient inspection can ensure the quality of the cell phone screen and enhance the user experience. So, what kind of lens should be selected for screen printing inspection of cell phone screens?

1, We need to consider the precision requirements of the inspection. Cell phone screen screen printing usually has a fine pattern and tiny features, which requires the lens to be able to provide high resolution and clear imaging.

2, The light conditions of the inspection environment will also have an impact on the choice of lens. Different lighting may lead to differences in contrast and brightness of the image, so the lens needs to have good optical performance to adapt to various environments.

3, The speed and efficiency of detection is also a key factor. A lens that can quickly obtain a clear and accurate image can greatly improve the efficiency of detection and reduce production costs.

So what kind of lens can meet these demanding requirements?

The answer is telecentric lenses.

Telecentric lenses offer several outstanding advantages:

1、High resolution: the ability to clearly capture minute silkscreen details ensures accurate inspection.

2、Low aberration: the imaging is almost free of aberration, which ensures the authenticity of the image and the accuracy of the measurement.

3、Constant magnification: not affected by the working distance, making the measurement results more stable and reliable.

POMEAS telecentric lenses are particularly good at this. We have a wide range of products to meet the needs of different inspection scenarios. Moreover, POMEAS telecentric lenses have been successfully applied in screen screen printing inspection of many cell phone manufacturers. After using Bumis telecentric lenses for screen printing inspection, the product quality has been significantly improved, the inspection efficiency has been dramatically increased, the defective rate has been effectively reduced, and the cost for the enterprise has been saved and the market competitiveness has been enhanced.
