Optical surface accuracy is an important index to determine whether optical components accord with requirements. Peak-to-valley (PV) value used as an evaluation standard is the difference between the highest point and the lowest point of the surface. PV value detected by UA3P detector has great variation, which is easy to be affected by environment. In order to evaluate the accuracy of mobile phone lens aspheric surface more effectively, three evaluation standards of PV, PV20 and PVq to reflect the actual surface are discussed through experiments. The results show that PV20 and PVq are relatively insensitive to environment factors and the adverse effects on measurement results from singular points such as dirty points can be eliminated to some extent. Meanwhile, it is proved that PV20 and PVq are relatively insensitive to detection accuracy variation and they have better evaluation stability in batch production.
