Abstract

A dry ice cooled 15-cm ir telescope was used on board the balloon-borne gondola THISBE for absolute surface photometry of the Milky Way, the zodiacal light, and the airglow in the PbS wavelength region. The mechanical, optical, electronical, and thermal design of the instrument is described. The efficiency of the baffle system for suppression of stray light from earth and balloon is discussed in detail. Recent airglow measurements are presented.

摘要

在搭载于气球吊舱“提斯柏”上的设备中，使用了一台由干冰冷却的15厘米红外望远镜，用于对银河系、黄道光以及铅硫化物波长区域的气辉进行绝对表面光度测量。文中描述了该仪器的机械、光学、电子和热学设计。详细讨论了用于抑制来自地球和气球的杂散光的遮光系统的效率。还给出了近期气辉测量的结果。
