A series of magnetically focused, electronographic image converters has been developed for use in far-uv photography and spectroscopy. The use of internal reflecting optics has enabled full advantage to be taken of the very high quantum yields of front-surface alkali halide photocathodes, resulting in over-all detection efficiencies a factor of 10 to 30 higher than similar systems using SC-5 film. An all-reflecting objective spectrograph using this system with Schwarzchild optics has been constructed for obtaining stellar spectra in the 1000-1400-A wavelength range, as well as a similar system based on Schmidt type optics for stellar spectroscopy in the 1230-2000-A wavelength range. Also, smaller Schmidt type instruments have been developed for direct stellar photography in the far uv.
已开发出一系列磁聚焦电子图像转换器，用于远紫外摄影和光谱学。内部反射光学器件的使用使得能够充分利用前表面碱金属卤化物光电阴极的非常高的量子产率，从而使整体检测效率比使用SC - 5胶片的类似系统高出10至30倍。已构建了一种使用该系统和施瓦兹希尔德光学器件的全反射物镜光谱仪，用于在1000 - 1400埃波长范围内获取恒星光谱，以及一种基于施密特型光学器件的类似系统，用于在1230 - 2000埃波长范围内进行恒星光谱学研究。此外，还开发了较小的施密特型仪器用于远紫外直接恒星摄影。
