ABSTRACT:
A quartz rod used as an optical wave guide to direct radiation of a desired spectrum onto a limited area, such as a dental cavity filled with a material curable by the radiation, is protected by a case including at least two rigid shells which tightly enclose the quartz rod but are easy to disassemble for being cleaned, and easy to reassemble thereafter. The interior wall of the case formed by the shells is spaced from the outer surface of the quartz rod except at a few points at both ends of the case, to leave the total reflection characteristics at the quartz rod surface unaffected.
