If the liquid has been degassed and is irradiated with a standing acoustic wave, a single bubble sonoluminescence (SBSL) can be generated. To study of SBSL, some emission detecting devices were set up. A Photo multiplier tube (PMT) successfully detected SBSL emission. However, collecting of light quantity is very low. Therefor it does not lead to the emission spectrum acquisition using the spectroscope. We increase collecting of light quantity by squeezing a collecting spot and observe SBSL emission spectroscopy.
