Optical module

An optical module comprising:

• a light-forming part configured to form light;
• a protective member that includes an output window configured to transmit light from the light-forming part and that is disposed so as to surround the light-forming part;
• an adapter connected to the protective member and including an optical passage through which light emitted from the light-forming part and transmitted by the output window passes;
• and
• an optical coupling component that is connected to the adapter and that light passing through the optical passage enters,
• wherein the light-forming part includes
• a semiconductor light-emitting device, and
• a lens configured to convert, in terms of spot size, light emitted from the semiconductor light-emitting device,
• wherein the optical coupling component includes
• an optical component, and
• a support member supporting the optical component, and
• wherein the support member and the adapter are connected together.
