Abstract
In cellphone optical systems, a tiny difference of manufacturing has a strong influence on camera lenses. This study aims to find out the worst result by tolerances come from all parts in optical performance. First, 3D Measure Instrument, Roundness Measure Instrument, and Wavelength Measure Instrument were used for greater precision by making and measuring the parts to see how different from the drawings. It was confirmed that even narrow tolerances could result in defects by assembling. Tolerances in assembly should be concerned as those in parts through the research.
