| 摘 要： | 详细讨论了薄透镜形状及透镜两侧介质对透镜的会聚与发散的影响 :当透镜两侧介质确定但不相同时 ,透镜的会聚与发散不但与透镜的凸、凹有关 ,而且与透镜及透镜两侧介质的折射率的相对大小有关 .特别是当像方折射率大于物方折射率时 ,会出现一些特殊情况

| Abstract: | The effects of lens shape and medium on both sides of lens for lens collecting and divergence are discussed in detail.As a result,when the medium on both sides of lens are fixed but different,lens collecting and divergence not only related to lens shape,also related to the refractive index of medium and lens.Some particular results will happen when refractive index in image space is bigger than that in object space. |
