概述“透镜板”是彩色油膜光阀电视中一重要零件,此仪器中有第一透镜板和第二透镜板透镜板(零件简图见图1)是由640个微粒透镜组成,微粒透镜布置如图2所示。微粒透镜分布在有相等曲率半径的曲面上(凸面或凹面上)各微粒透镜有一个相等的曲率半径,且各微粒透镜光轴均通过一个共同的曲率中心(即大球面的曲率中心)。为了实现这一要求的透镜板,有的单位曾采用由几百个小透镜磨成四方块排列粘结在大透镜上的方法,这种方法需要磨出几百个小透镜,并且在磨外形之后粘结在一起,既麻烦又费工,而且粘结后的质量很难保证,工艺上困难也是很大的,美国的彩色油膜光阀电视样机上的透镜板是采 Overview “Lens plate” is an important part of the color film light valve TV, the instrument has the first lens plate and the second lens plate lens plate (parts schematic diagram in Figure 1) is composed of 640 micro-lens, particle lens arrangement as shown in picture 2. Particle lenses are distributed on curved surfaces (convex or concave) with equal radii of curvature. Each particle lens has an equal radius of curvature, and the optical axis of each particle lens passes through a common center of curvature (ie, the center of curvature of the large spherical surface). In order to achieve this requirement of the lens plate, some units have been used by the hundreds of small lens grinding into four-block arrangement bonded to the large lens method, this method requires grinding out hundreds of small lenses, and the grinding profile After bonding together, both cumbersome and laborious, but also difficult to ensure the quality of the bond, the process is also very difficult, the United States color film light valve TV prototype on the lens board is adopted
