Optical module

An optical module comprising:

• a light emitting unit configured to generate light;
• a mirror mechanism configured to reflect the light generated by the light emitting unit;
• and
• a scanning unit configured to scan the light reflected from the mirror mechanism,
• wherein the light emitting unit includes:
• a light forming unit including a plurality of laser diodes and a filter configured to multiplex light beams from the plurality of laser diodes;
• and a protective member disposed so as to surround the light forming unit,
• wherein the mirror mechanism is disposed outside the protective member, integrated with the protective member, and includes a mirror configured to reflect the light generated by the light emitting unit and a mirror holder placed on the protective member and holding the minor,
• wherein the scanning unit is disposed in a region surrounded by the protective member,
• wherein the protective member has:
• a first window from which the light directed from the light emitting unit toward the mirror mechanism is emitted;
• and a second window through which the light reflected from the mirror mechanism and directed toward the scanning unit enters, and
• wherein the light scanned by the scanning unit is emitted to the outside of the protective member through the second window.
