【Abstract】 A design method of concentrator is presented.The optical gain and FOV of hemispherical concentrator and spherical cap concentrator of truncation angle which is not 90 degrees have been computed and discussed,and the principle of choosing good truncation angle is proposed.The optical intensity distribution on circle section of hemispherical concentrator in uniform diffusing illuminance has been computed and analyzed,and the principle of basic parameters selecting right hemispherical concentrator is proposed.The condition has been found using optical theory,the optical light reaching photoconductive surface must meet,and its significance to optical filter has been discussed.更多还原
