OPTICAL AXIS IDENTIFYING APPARATUS FOR EXPOSING DEVICE AND EXPOSING DEVICE WITH THE SAME

摘要

An optical axis identifying apparatus for an exposure device is provided to be embodied at a low cost by using a few mirrors and lenses, and to identify the exact position of a light source by identifying an optical axis with the naked eye. An optical axis identifying apparatus for an exposure device includes: a housing(310) which has a fine hole(311) provided to receive a point light from a light source; at least one lens(300) which refracts and focuses a light introduced through the fine hole; and a screen(340) which has a reference display part(341) so as to identify an optical axis, and on which an image is projected by the light refracted by the lens.
