The infrared lenses, suitable for the use at very low temperature (below 70K) and for the astronomical observations in the mid-infrared, have been developed. The following activities were done :1) KRS-5 refractive index measurements at low temperatureThe KRS-5 refractive index below 70K is not available in the literature, so we measured it using the Fabry-Perot interference method.2) Design, ＆ fabrication of the lenses of proto-type mid-infrared cameraThe mid-infrared camera optics have designed , and the proto-type lenses have been fabricated.3) establish the alignment technique of the cooled cameraThe adjustment at optics has done at room temperture, but the camera should be used around 5-10K.So thermal distortion must be avoided.4) presentation in the international symposiumDevelopment and the status of the camera have been reported in a few international symposium.

研制了适用于极低温（70 K以下）和中红外天文观测的红外透镜。本文主要完成了以下工作：1）低温下KRS-5折射率的测量KRS-5折射率在70 K以下的折射率在文献中没有报道，因此我们采用法布里-珀罗干涉法进行了测量。2）中红外相机原型镜头的设计与制作设计了中红外相机的光学系统，并制作了原型镜头。3）建立了冷却相机的装调技术光学系统的调整已经在室温下完成，但相机必须在5 - 10 K左右使用，因此必须避免热畸变。
