Claim 1
Independent Claim
121 words
APPARATUS FOR IRRADIATING A SPECIMEN TO BE EXAMINED BY FLUORESCENCE MICROSCOPY, SAID APPARATUS COMPRISING A SOURCE OF ULTRAVIOLET RADIATION, A RADIATION-TRANSMITTING DEVICE EMBODYING A MULTIPLICITY OF RADIATION-CONDUCTING FIBERS ASSEMBLED IN SPACED SIDE-BY-SIDE RELATION WITHIN A RADIATION-INSULATING MATRIX, SAID DEVICE HAVING ONE END DISPOSED FOR RECEIVING RADIATION FROM SAID SOURCE WITHIN SAID FIBERS AND HAVING ITS OTHER END DISPOSED FOR DIRECTING RADIATION TRANSMITTED THERETHROUGH UPON THAT PORTION OF SAID SPECIMEN TO BE EXAMINED MICROSCOPICALLY, RADIATIONINTEGRATING MEANS DISPOSED IN SURROUNDING RELATION TO SAID SOURCE AND TO SAID RADIATION-RECEIVING END OF SAID DEVICE FOR DIRECTING SUBSTANTIALLY ALL RADIATION FROM SAID SOURCE UPON SAID RADIATION-RECEIVING END AT DIVERSE ANGLES, AND FILTER MEANS DISPOSED IN SEQUENCE WITH SAID DEVICE FOR PERMITTING TRANSMISSION OF ULTRAVIOLET RADIATION ONLY.
