摘要
在ＨＤＴＶ投影管的荧光层与玻璃屏之间，蒸镀上多层光学干涉膜。它一方面能提高色纯度；另一方面能集中光能于较小的立体角内，从而提高投影效率。本文叙述该于涉膜的设计思想和计算方法。
A multilayer interference film is employed between phosphor layer and faceplate of the projection TV tubes.On the one hand this technique can be used to improve color purity,and on the other hand it can also concentrate energy of light on a small emitting direction to improve efficiency of projection. This article describes the design and calculating method of the film.
