1. A light emitting apparatus that is supported by a second support supported by a first support laterally relative to the first support alongside an imaging apparatus and that emits light to be detected by the imaging apparatus, the light emitting apparatus comprising:
a light source that emits the light;
a lens on which the light emitted from the light source is incident and that transmits the light incident on the lens;
a screen disposed between the light source and the lens; and
a substrate including a placement surface on which the light source is placed, wherein
the lens includes a part provided with a dimmer that at least partially reduces light to be emitted to the first support out of the light incident on the lens, and
the screen includes:
a light shield disposed between the lens and the light source at a position closer to the first support than the light source is to at least partially absorb, reflect, or diffuse the light traveling to the part of the lens located adjacent to the first support out of the light emitted from the light source; and
a flat portion placed on the placement surface between the lens and the placement surface.
