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.

我们开发了一种设备，用于使用碘气体过滤器和CCD单色器在低频区域测量拉曼散射。通过在合适的温度下通过气体过滤器的散射光，激光束的散射光强度被降低至1/1000。 但是，减少的幅度随着时间而显着变化。 原因将是激光头温度的稳定性。 我们还使用霓虹灯气体的一些发射线检查了CCD单色器的分辨率，并确认它具有足够的分辨率（1.7 cm-1）来测量拉曼散射。 此外，我们通过检查合适的条件成功地在乙炔等离子体中成功产生了灰尘颗粒。
