<p>A compact, easy to use apparatus for irradiating an object such as a specimen of material with ultraviolet radiation at a selected long, short or mid-wave length. The apparatus of the invention includes a plurality of ultraviolet sources (14a,14b,14c), each emitting radiation at a different wave length. The sources (14a,14b,14c) are mounted within a rotatable array (12) so that a selected one of the sources can be sequentially moved into alignment with the specimen and then automatically energized by merely rotating the array.</p> |
