摘要：介绍了一台口径为1.23m光电望远镜的Coude光学系统,通过比较国内外地基大口径望远镜Coude光学系统的形式,结合实际情况,设计了以离轴非球面反射镜作为二次成像元件的Coude光学系统,并给出了相应的检测和装调的方法.经实际检测和装调对准后,对Coude光学系统的设计、检测和装调对准过程中的误差进行了分析和比较,证明了检测与装调方法的可靠性和先进性.该Coude光学系统的焦距为125m,视场为1.5′,波段为0.4~5μm,系统波像差优于λ/50（λ=0.632 8μm）,实验室内检测波像差为λ/20.装调对准完成后对恒星观测,用Shack-Hartmann波前探测器测量其波前误差,得到整个望远镜Coude光学系统的波像差优于λ/4.

摘要：A novel element for collimating LED light is designed based on non-imaging optics. It is composed of a refraction lens and a reflector. The upper surface of the lens is freeform and calculated by geometrical optics and iterative process. The lens makes the rays in the range of 0°-45°from the optical axis collimated. The rays in the range of 45°-90°from the optical axis are collimated by the reflector. The inner surface of the reflector is parabolic with its focus located in the LED chip. The designed element is applicable to LED source of any emitting type. For a certain application, the simulation results of the designed element in Tracepro show that it has a very compact structure and good collimating performance. Just investigating the loss in the lens surfaces, this element has high light output efficiency of nearly 99%. Most lighting area radii are no more than 20 mm when the illuminated plane is 5 m away from the LED source.
