An internet phone system includes an internet phone main body, an expansion device and a multiple-layer connecting card. The internet phone main body includes a first connecting port. The at least one expansion device includes a second connecting port. One end of the multiple-layer connecting card is connected to the first connecting port, and the other end is connected to the second connecting port such that the internet phone main body can be electrically connected to the expansion device via the multiple-layer connecting card. The expansion device is capable of combining with another expansion device by another multiple-layer connecting card.

An integrating sphere ellipsometer includes an incident light polarization control unit, a reflective light polarization analysis unit, an integrating sphere and a total integrated scattered light detector. The incident light polarization control unit and the reflective light polarization analysis unit jointly function as an ellipsometer to obtain information such as film thickness and material complex refractive indices. Concurrently, the identical incident light polarization control unit, the total integrated scattered light detector and the integrating sphere unite to function as an integrating sphere analyzer to measure material defects, surface roughness, surface particulates, micropollutants, etc.
