Abstract:
(EN) This optical module is provided with a mirror unit and a beam splitter unit. The mirror unit is provided with: a base having a main surface; a movable mirror; a first fixed mirror; and a drive unit. The beam splitter unit, the movable mirror, and the first fixed mirror form a first interference optical system for measurement light. A mirror surface of the movable mirror and a mirror surface of the first fixed mirror extend in a plane parallel to the main surface, and face one side in a first direction orthogonal to the main surface. The movable mirror, the drive unit, and at least a portion of the optical path between the beam splitter unit and the first fixed mirror are disposed in an airtight space.
(FR) La présente invention concerne un module optique comportant une unité de miroir et une unité de diviseur de faisceau. L'unité de miroir comporte : une base présentant une surface principale ; un miroir mobile ; un premier miroir fixe ; et une unité d'entraînement. L'unité de diviseur de faisceau, le miroir mobile et le premier miroir fixe forment un premier système optique d 'interférence destiné à la lumière de mesure. Une surface de miroir du miroir mobile et une surface de miroir du premier miroir fixe s'étendent dans un plan parallèle à la surface principale et se trouvent en regard dans une première direction orthogonale à la surface principale. Le miroir mobile, l'unité d'entraînement et au moins une partie du chemin optique entre l'unité de diviseur de faisceau et le premier miroir fixe se trouvent dans un espace étanche à l'air.
(JA) 光モジュールは、ミラーユニットと、ビームスプリッタユニットと、を備える。ミラーユニットは、主面を有するベースと、可動ミラーと、第1固定ミラーと、駆動部と、を有する。ビームスプリッタユニットは、可動ミラー及び第1固定ミラーと共に測定光について第1干渉光学系を構成している。可動ミラーのミラー面及び第1固定ミラーのミラー面は、主面に平行な平面に沿っており、主面に垂直な第1方向における一方の側に向いている。可動ミラー及び駆動部、並びに、ビームスプリッタユニットと第1固定ミラーとの間の光路の少なくとも一部は、気密空間に配置されている。
