IRRADIATION APPARATUS

PURPOSE: To provide an irradiation apparatus constituted to move the position of a spot light source in its optical axis direction in such a manner that irradiation light from this spot light source is reflected by a reflection mirror so as to be made into parallel rays.

Zusammenfassung:	PURPOSE: To provide an irradiation apparatus constituted to move the position of a spot light source in its optical axis direction in such a manner that irradiation light from this spot light source is reflected by a reflection mirror so as to be made into parallel rays. CONSTITUTION: A mounting bar 7 mounted with a UV lamp 1 is inserted into the center of a lamp holder 5 and is supported freely rotatably by a bearing 6. This lamp holder 5 is provided at its both ends with adjusting screws 4. The lamp holder 5 is moved by rotating these adjusting screws 4, by which the relative position of the UV lamp 1 and the reflection mirror 2 which is a paraboloid of revolution is adjusted. The UV lamp 1 is thus placed at the focal position of the reflection mirror 2 and the irradiation light thereof has the uniform illuminance to a photosensitive resist surface.
