PROBLEM TO BE SOLVED: To solve the problem that there is a risk that welding sputter is attached to a lens of an imaging device and welding fume clouds the lens of the imaging device when imaging the state of welding with the imaging device and performing profile compensation of a teaching position based on an imaged image and, further, there is a risk that defective welding occurs due to influence of shield gas in the conventional technique in which shield gas used when performing welding is utilized in order to prevent attachment of the welding sputter or welding fume to the lens.SOLUTION: An optical device includes: a cover member having an opening part; and one or a plurality of optical members which are covered with the cover member, contain one area corresponding to the opening part and are configured such that one area can be changed. By means of the optical device configured in such a manner, an imaging device can be protected while reducing a risk of causing defective welding.SELECTED DRAWING: Figure 4 【課題】溶接の状態を撮像装置で撮像し、撮像画像に基づいて教示位置の倣い補正を行う場合、溶接スパッタが撮像装置のレンズに付着したり、溶接ヒュームが撮像装置のレンズを曇らせたりするおそれがある。溶接を行う際に用いるシールドガスを利用して、レンズへの溶接スパッタや溶接ヒュームの付着防止を図る従来技術では、シールドガスの影響により溶接不良が生じるおそれがある。【解決手段】本発明の光学装置は、開口部を有するカバー部材と、カバー部材により覆われるとともに、開口部に対応する一の領域を含み、一の領域を変更可能に構成された１または複数の光学部材とを備える。このように構成した光学装置によって、溶接不良が生じるおそれを低減しつつ撮像装置を保護することができる。【選択図】図４
