In today's competitive smartphone market, the quality and accuracy of the rear camera is critical. In order to ensure the excellent performance of a cell phone's rear camera, high-precision measurements become a key component.

In this case, the measurements required include the roundness of the camera, the diameter, the curvature, the distance difference between the inner circle and the outer circle, and the straight line distance between the lens frames. Moreover, the measurement accuracy required was an astonishing 1um.

In order to meet such demanding measurement requirements, we use the POMEAS IMAGE3 PRO measuring instrument. This state-of-the-art measuring instrument offers excellent performance and precise measurement capabilities.

For roundness measurement, it accurately captures the slightest deviation from the rounded contour, ensuring that the camera's rounded parts meet strict standards. For diameter measurement, its high-precision sensors and advanced algorithms provide extremely accurate data.

For curvature measurements, the POMEAS IMAGE3 PRO Gauge is able to analyze the changes of the curve in a delicate way to ensure that the curved part of the camera meets the design requirements. When measuring the distance difference between the inner circle and the outer circle, it can accurately distinguish the small differences to ensure the concentricity and stability of the lens.

The same excellent accuracy and reliability is demonstrated in the measurement of straight-line distances between lens frames.

By using the POMEAS IMAGE3 PRO measuring instrument, we have successfully realized the high-precision measurement of various parameters of the rear camera of the cell phone, which provides a strong support and guarantee for the improvement of the quality and performance of the cell phone camera.
