摘　　要：光锥可以弥补场镜、光纤在光电探测仪器中光线传输汇聚的弊端,光锥传输光线不但损失小,而且可以把光阑后面的光线根据需求分开传输。通过光锥的应用,使光电探测器的灵敏度大幅增强。叙述了光锥的传输特性和设计方法。The cone of optics can make up the disadvantage,that the field lens and optical fiber in the photoelectric detection instrument the light transmission and gathering.The cone of optics transmission light loses slightly,moreover it can separate the light to transmission behind light diaphragm to the demand.Through appling the cone of optics,large sensitivity enhancementin the photoelectric detection instrument.The cone of optics transmission characteristic and the desing method are narrated.
