Abstract

An optical module includes a light-forming part; a protective member and including an output window and 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. The light-forming part includes semiconductor light-emitting devices and lenses configured to convert, in terms of spot size, light emitted from the semiconductor light-emitting devices. The optical coupling component includes an optical component and a support member supporting the optical component. The support member and the adapter are connected together.

First claim
