The infrared spectrometer that recorded spectra of the atmosphere and surface of Mars during the Mariner 6 and 7 flyby missions is described. The instrument continuously scanned the 1.9-micro to 14.4-micro spectral region at 10 see per scan. Approximately 1% spectral resolution was furnished by two rotating, circular, variable interference filters. The spectral region 1.9-6.0 micro was recorded with a PbSe detector cooled to 175 K by radiation to deep space. The spectral region 3.9-14.4 micro was modulated by a cold (175 K) tuning fork chopper and recorded with a mercury-doped germanium detector cooled to 22 K by a Joule-Thomson two-stage (N(2) and H(2)) cryostat. The total weight of the instrument was 17.4 kg (monochromator plus electronics, 11.5 kg; gas delivery system, 5.9 kg), and it consumed 11 W of power.
描述了在“水手6号”和“水手7号”飞越任务期间用于记录火星大气和表面光谱的红外光谱仪。该仪器以每次扫描10秒的速度连续扫描1.9微米至14.4微米的光谱区域。由两个旋转的圆形可变干涉滤光片提供约1%的光谱分辨率。1.9 - 6.0微米的光谱区域由一个通过向深空辐射冷却至175K的PbSe探测器记录。3.9 - 14.4微米的光谱区域由一个冷（175K）音叉斩波器调制，并由一个通过焦耳 - 汤姆逊两级（N₂和H₂）低温恒温器冷却至22K的汞掺杂锗探测器记录。该仪器的总重量为17.4千克（单色仪加电子设备，11.5千克；气体输送系统，5.9千克），功耗为11瓦。
