Abstract

　溶接アーク放電下において、溶接状態を確認するためにアーク放電光をフィルタリングする光学系として、テレセントリック光学系とフォトクロミックフィルタ（ＰＣＦ）による部分減光を使用し、ＰＣＦ上で結像させず、ＰＣＦ上から焦点がずれても減光性能を確保でき、溶接状態のモニタリングが良好な溶接観察装置を提供する。 　アーク溶接部８と、アーク溶接部８からの光を集光する対物光学系（１，２）と、対物光学系（１，２）により集光した光を導光するテレセントリック光学系３と、テレセントリック光学系３によって導光された光を照射するＰＣＦ４と、ＰＣＦ４を透過した光を受光する固体撮像装置９とを備え、ＰＣＦ４により、アーク溶接部８からの光を、部分減光する。
