一实施例中，第一镜片2与第二镜片7相互抵接，以便第一镜片2与第二镜片7之间相互传导热量，在加热时实现同步升温的效果。具体地，由于第一镜片2与第二镜片7之间的空隙可能存在水汽，虽然第二镜片7的温度随气温变化的起伏没有第一镜片2明显，但雾珠同样可能凝结于第二镜片7上，因此第一镜片2与第二镜片7相互抵接，第一镜片2可以向第二镜片7传导热量，使第二镜片7随之升温，对第二镜片7起到除雾的效果。
可选的，快速除雾光学装置还包括第三镜片8和第四镜片9，第三镜片8和第四镜片9并排设置于安装镜框1的通孔中，且均位于第二镜片7背离第一镜片2的一侧，第三镜片8和第四镜片9均与安装镜框1的内壁抵接。
可选的，第三镜片8和第四镜片9之间还设有隔圈11，隔圈11的中部设有通光孔111，通光孔111的内壁上设有导光阶梯结构112，用于调整光线的入射方向。
可选的，快速除雾光学装置还包括滤光片12，滤光片12设于安装镜框1的通孔中，滤光片12位于第一镜片2和感光芯片10之间，滤光片12用于筛取所需波段的光线。
