We developed an equipment for measuring Raman scattering in a low-frequency region using an iodine gas filter and a CCD monochromator. The intensity of scattering light of a laser beam was reduced to 1/1000 by the scattering light passing through the gas filter kept under a suitable temperature. However, the magnitude of reduction significantly changed with time. The reason would be the stability of temperature of the laser head. We also checked the resolution of the CCD monochromator using some emission lines from neon gas and confirmed that it has an enough resolution (1.7 cm-1) for measuring the Raman scattering. In addition, we successfully produced dust particles in an acetylene plasma by examining suitable conditions.

我们研制了一种用碘气体滤光片和CCD单色器测量低频区拉曼散射的装置。激光束的散射光的强度通过穿过保持在适当温度下的气体过滤器的散射光而减小到1/1000。 然而，随着时间的推移，减少的幅度发生了显著变化。 原因是激光头的温度稳定性。 我们还使用来自氖的一些发射线检查了CCD单色仪的分辨率，并确认其具有足够的分辨率（1.7 cm-1）用于测量拉曼散射。 此外，我们成功地产生了粉尘颗粒在乙炔等离子体通过检查合适的条件。
