Abstract
An optical module includes a light-forming unit configured to form light, and a protective member surrounding and sealing the light-forming unit. The light-forming unit includes a laser diode, a first MEMS including a first mirror having a first reflective surface that reflects and scans light from the laser diode, the first mirror oscillating to form a first plane, and a second MEMS including a second mirror having a second reflective surface that reflects and scans light from the first mirror, the second mirror oscillating to form a second plane orthogonal to the first plane.

A scanning optical module comprising:
- a light-forming unit configured to form light;
- and
- a protective member surrounding and sealing the light-forming unit;
- the protective member including
- a base body having a flat plate shape and a main surface,
- a lid disposed on the main surface and having a window portion in a region of the lid facing the main surface, the window portion penetrating through the lid, and
- a window closing the window portion,
- the light-forming unit including
- a laser diode,
- a first MEMS including a first mirror having a first reflective surface that reflects and scans light from the laser diode, the first mirror oscillating to form a first plane with a trajectory of a first normal which is a normal at a center point of the first reflective surface, and
- a second MEMS including a second mirror having a second reflective surface that reflects light from the first mirror toward the window portion and scans light from the first mirror, the second mirror oscillating to form a second plane orthogonal to the first plane with a trajectory of a second normal which is a normal at a center point of the second reflective surface.
