Abstract:
1. An optical intermediary component, suitable for guiding a light from an output optical path into an input optical path, wherein a width of the output optical path is greater than a width of the input optical path, the optical intermediary component comprising: a light guiding portion, extending along a light axis, and having a light incident surface coupled to the output optical path and a light emitting surface coupled to the input optical path at two opposite ends thereof respectively, wherein the light from the output optical path passes through the light incident surface and the light emitting surface in sequence and is then guided into the input optical path, and an area of the light incident surface is greater than that of the light emitting surface, the light guiding portion further comprising: an inner core, extending along the light axis, wherein an end of the inner core forms the light emitting surface; and an outer core, surrounding the inner core along the light axis, and the light is transmitted in both of the inner core and the outer core.
