- W2391955868 abstract "Optical surface accuracy is an important index to determine whether optical components accord with requirements. Peaktovalley(PVvalue used as an evaluation standard is the difference between the highest point and the lowest point of the surface. PV value detected by UA3 P 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 PVPVand PVq to reflect the actual surface are discussed through experiments. The results show that PVand 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 PVand PVq are relatively insensitive to detection accuracy variation and they have better evaluation stability in batch production." @default.
