In Antarctica the cold and dry air is expected to provide the best observing conditions on the Earth for astronomical observations from infra-red to sub-millimeter. To enjoy the advantages in Antarctica, we have a plan to make astronomical observations at Dome Fuji, which is located at inland Antarctica. However, the harsh environment is very problematic. For example, the temperature comes down to as low as-80 degree Celsius in winter, where instruments designed for temperate environment would not work. In this context, we have developed a 40cm infra-red telescope, which is dedicated for the use even in winter at Dome Fuji. In designing the telescope, we took account of the difference of the thermal expansion rate among materials, which were used for the telescope. Movable parts like motors were lubricated with grease which would be effective at-80degrees. Most parts of the telescope are made of aluminum to make the telescope as light as possible, so that it makes the transportation from seacoast to inland and assembling at Dome Fuji easier. We also report the experiment that we have done at Rikubetsu (the coldest city in Japan) in February 2008. Details the design process for AIR-C, the Antarctic Infra-Red Camera, for use with Tohoku University's 40cm Antarctic telescope were designed. The camera will also be compatible with the planned 2 meter class Japanese telescope at Dome F. First, we reviewed of the design requirements which shaped the development process. The effect of cryogenic temperatures on the lenses was taken into account during the design process. AIR-C's performance is predicted. Finally, we discussed the scientific potential for a small Antarctic telescope.

在南极洲，预计冷和干燥的空气可为地球上的最佳观察条件提供从红外到亚毫米至亚毫米计的天文观测。为了享受南极洲的优势，我们有一个计划在位于南极内陆的圆顶富吉（Dome Fuji）进行天文观察。但是，恶劣的环境非常有问题。例如，冬季，温度降至低至80度的摄氏摄氏度，在这里为温带环境设计的仪器无法正常工作。在这种情况下，我们已经开发了40厘米红外望远镜，即使在冬季在富士圆顶，它也专门用于使用。在设计望远镜时，我们考虑了用于望远镜的材料之间的热膨胀速率的差异。像电动机这样的可移动零件用油脂润滑，这将是有效的AT-80度。望远镜的大多数部分都是由铝制成的，以使望远镜尽可能轻巧，因此它使从海岸到内陆的运输和在富士圆顶上组装的运输更加容易。我们还报告了2008年2月在Rikubetsu（日本最冷的城市）进行的实验。详细介绍了Air-C（南极红外摄像头）的设计过程，供Tohoku University与Tohoku University的40厘米南极望远镜一起使用。该相机还将与圆顶F的计划的2米级日本望远镜兼容。首先，我们回顾了塑造开发过程的设计要求。在设计过程中考虑了低温温度对镜片的影响。预计AIR-C的性能。最后，我们讨论了小南极望远镜的科学潜力。
