To "''narrow''" can mean either to cause the directions of motion to become more aligned in a specific direction (i.e., make collimated light or parallel rays), or to cause the spatial cross section of the beam to become smaller (beam limiting device). ==History== An English physicist Henry Kater was the inventor of the floating collimator, which rendered a great service to practical astronomy. He reported about his invention in January 1825.〔(The Description of a Floating Collimator. By Captain Henry Kater. ) Read January 13, 1825. (Trans. 1825, p. 147. )〕 In his report, Kater mentioned previous work in this area by Carl Friedrich Gauss and Friedrich Bessel. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Collimator」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
