| Abstract: | The feature and specification of the lens system used to measure screen characteristics of high resolution display tube are described in this paper. The difference between adjust location and focal length of the lens system is analysed. The expression for effect measuring precision due to change of screen thickness is derived. A design example is illustrated toshow good agreement between analysis and measured results. |
