Abstract:	本論文討論一具有高聚光倍率、輕量化、薄長形和零後焦長的特點的聚光鏡組，此設計可以使太陽能集光器系統的成本大大降低，不僅僅簡化了系統的複雜度，也對整個系統的重量降低。本論文描述兩種新型的太陽能集光器，第一種為OAR鏡組的設計，利用離軸拋物面鏡概念將邊緣光線逐漸會聚到中心區域，其厚薄比可以達到5:1的比值。第二種為TIR鏡組的設計，利用全反射原理讓光經由兩次反射到達接收面上，其厚薄比可以達到6:1的比值。此兩種集光器都可以具有零後焦長的特性，利用光學軟體的輔助設計之下可以模擬到光學效率分別為66.57% 和77.68%。 This paper discusses the high Concentrating ratio, lightweight, long thin shape and the back zero focal distance features after the condenser lens group, this design can make the solar concentrator system cost greatly reduced, not only simplifies the complexity of the system, but also reduce the weight of the entire system. This paper describes two new solar concentrator, the first lens module for the design is OAR, the use of the concept of off-axis parabolic mirror to the edge of the light gradually converging to the center area, and the thickness ratio can reach 5:1 ratio. Then, the second lens module for the design is TIR, the use of optical principle of total reflection to reach the receiver via two reflecting surface, the thickness ratio of 6:1 ratio can be achieved. These two concentrator can have the characteristics of the focal length of zero after using of optical software can be simulated the optical efficiency were 66.57% and 77.68%.
