摘　　要：针对卡塞格林太阳能聚光镜的次镜遮挡问题,提出了降低遮拦比的透镜校正法。在传统的聚光比与遮拦比计算公式的基础上,给出了校正版计算公式。选取聚光比为280,遮拦比为0.33的卡塞格林聚光镜,利用Zemax软件进行了仿真分析。结果表明利用透镜校正法,所设计的卡塞格林聚光镜的遮拦比降低了36.36%,并且聚光镜的聚光比也得到了改善,接收器表面的光斑分布也更加均匀。For solving the problem of secondary lens occlusion in Cassegrain solar condenser,a lens correction method was proposed to reduce the obscuration ratio.On the basis of the traditional concentration ratio and obscuration ratio formula,the correction formulas were proposed.A Cassegrain condenser was analyzed with Zemax software,the concentration ratio was 280,and the obscuration ratio was 0.33.The results showed that using lens correction method,the obscuration ratio of the designed Cassegrain condenser was reduced by 36.36%,the concentration ratio of the condenser was improved,and the spot distribution on the receiver surface was more uniform.
