Design of large aperture ultraviolet optical system for ultraviolet camera
摘要
Abstract
In order to solve the problems such as the deficiency of positioning and pointing accuracy, large chromatic aberration,insufficient resolution and energy utilization efficiency, a high-resolution large aperture achromatic UV optical system is designed. First, based on the application requirements of corona discharge detection,the overall design requirements of UV optical system are proposed. Then,using the different disper-sion characteristics of both fused silica and calcium fluoride,a large aperture achromatic UV optical system is designed according to the improved double-cemented lens structure,and the tolerance analysis of the system is carried out. The results show that the ultraviolet optical system designed in this paper has a dot-matrix root mean square diameter less than 0.08 mm and a resolution of 20 lp/mm within the full field of view, which meets the requirements of the power industry for corona detection.关键词
