摘要:
The invention provides an exposure head including: a light emitting unit; an imaging unit that allows light from the light emitting unit to enter through an incidence plane and exit from an exit surface so as to form an image at a predetermined position; and a transparent layer provided between the light emitting unit and the imaging unit, while contacting each of the light emitting unit and the imaging unit; the transparent layer having a thickness such that an optical distance between the light emitting unit and the incidence plane of the imaging unit becomes a working distance of the imaging unit.
