Abstract

In order to adjust and test 500 mm-caliber, 5m-focus resource satellite camera, basing on no focal-power adjustment, we have designed and produced a unique parallel light tube. This tube focus is 20 m, but tube-length is only 8 m different from an old by using magnifying-adjustment technology. Which is an internal pioneer, has a novel shape and longest focus. Because shorter tube length, it is influenced smaller by environment. The study open an new road to without taking out vacuum and low manufacturing expense. This paper introduces the key technology of design, adjusting and testing about the tube. At last relates manufacturing experience and improving thought.
