Abstract

An illuminator apparatus can include: an optical source a collimator lens located on an optical axis of the optical source, for receiving emitted light from the optical source to emit collimated light; and a diffusion lens, located on an emitting surface side of the collimator lens, for receiving the collimated light to diffuse the collimated light. The diffusion lens can be provided with a diffusion section for diffusing central light of the collimated light emitted from a central portion of an emitting surface of the collimator lens and a non-diffusion section for transmitting peripheral light of the collimated light emitted from an outside of the central portion of the emitting surface of the collimator lens, without diffusing the peripheral light.
