【摘要】 在光学元件中,由于元件表面的反射作用而使光能损失,为了减少元件表面的反射损失,常在光学元件表面镀层透明介质薄膜(增透膜).研究表明,许多学生对增透膜的增透原理存在错误理解,本文利用电动力学方面的知识分析增透膜增加透射的原理,并给出了单层薄膜增加透射的条件.更多还原

【Abstract】 The light energy will be lost due to the reflection of the lens`s surface in optical devices. A layer of medium film is plated on the surface of such devices (called film of increasing transmission or FIT) in order to reduce the loss of surface reflection. The result from the research indicates that students have mistakes about understanding the film of increasing transmission theory. Based on the electronmagnetic wave theory of light, this paper analyses and explains the film of increasing transmission theory of a single layer of media film, deduces and discusses the increasing transmission condition.更多还原
