A unique grazing incidence spectrometer system has been designed to study diffuse line emission between 80 and 650 A with 10-30 A resolution. The minimum detectable emission line strength during a 5-min observation ranges from 100-2000 ph cm(-2) sec(-1) str(-1). The instrument uses mechanically ruled reflection gratings placed in front of a linear array of mirrors. These mirrors focus the spectral image on microchannel plate detectors located behind thin filters. The field of view is 40 min of arc by 15 degrees , and there is no spatial imaging. This instrument has been fabricated, calibrated, and successfully flown on a sounding rocket to observe the astronomical background radiation.
设计了一种独特的掠入射光谱仪系统，用于研究80至650埃之间的漫射线发射，分辨率为10 - 30埃。在5分钟观测期间，最小可探测发射线强度范围为100 - 2000光子·厘米⁻²·秒⁻¹·斯特拉⁻¹。该仪器使用机械刻划的反射光栅，放置在镜子线性阵列的前面。这些镜子将光谱图像聚焦在位于薄滤光片后面的微通道板探测器上。视场为40角分×15度，且没有空间成像。该仪器已制造、校准并成功搭载探空火箭飞行，以观测天文背景辐射。
