| Abstract: | The optical properties of large aperture sol-gel chemical coatings were mainly determined by the thickness and refractive index of the films. The key technique of the process was precisely controlling the two parameters. By optimizing the preparation process of the colloid and measuring the change of the thickness and refractive index of the chemical film by ellipsometry, we obtained the pulling speed model and verified it experimentally, which provided technical and technological guarantee for the high performance index of the large-diameter chemical coatings. |
