摘    要:从分析透镜不同入射高处小棱镜在最小偏向角时具有面形形变容差大的特点出发,给出了柱面菲涅耳太阳聚光透镜对称折射设计的基本原理,并比较了对称折射设计透镜和常规设计透镜的透射特性和会聚特性。采用对称折射设计,菲涅耳透镜柱面形变容差通常可高达15°~20°,且具有比常规设计高的光学效率;对称折射设计透镜虽存在散焦问题,但只要参数选择合理,出射光线均可会聚在太阳电池片上。

关 键 词:聚光透镜  菲涅耳透镜  对称折射  空间太阳电池阵  航天器

Abstract:On account that the mall prism has the biggest facial contour deformation tolerance corresponding the smallest deviation angle at different incident height of lens,basic principal for symmetrical refraction design of arched Fresnel concentrator lens is presented,and the(transmittance) and convergent property of transmitted light for symmetrical design and conventional design are compared.The facial contour deformation tolerance of Fresnel lens can generally arrive at 15~20 degree by this design method,and it's optical efficiency is higher than that of conventional designed Fresnel lens,Although there is off-focus phenomenon for the Fresnel lens designed by symmetrical refraction,transmitted light can still be focused on the sloar cells if the parameters are selected properly.
Keywords:Condenser lenses Fresnel lenses symmetrical refraction(Space solar cell array) Spacecraft
