    摘要:

    用氮氧化铪薄膜作为CVDZnS衬底的保护膜、由YbF3和ZnS组成的增透膜系分别在CVDZnS的两面制备了保护膜和增透膜,研究了镀膜前后CVDZnS在8~12 μm波段的光学性能,单面镀制增透膜之后CVDZnS在此波段的平均透过率由未镀膜前的74%提高到了82%,峰值透过率大于83.5%。在CVDZnS上镀制HfON保护膜后,其8~12 μm波段透过率没有明显的降低,同时硬度测试表明HfON薄膜的硬度约为11.6 GPa,远大于衬底CVDZnS的硬度。胶带实验和泡水试验表明,制备的保护膜和增透膜均和衬底有

    Abstract:

    Hafnium oxynitride protective films and anti-reflection films were separately prepared onto double side of CVDZnS substrates.The optical properties of CVDZnS before and after coated AR in the region of 8~12μm were studied.After coated AR on the single surface of CVDZnS substrates,the average transmittance improved from 74% to 82% and the peak transmission of the films was more than 83.5%.After coated HfON protective films,the transmittance of HfON/CVDZnS/AR system had no obvious decreased in the region of 8~12μm and the hardness of HfON/CVDZnS system had the value of 11.6GPa which higher than the hardness of CVDZnS substrates.The HfON protective films and anti-reflection films had good adherence with the CVDZnS substrates.
