Abstract
A laparoscopic instrument is provided having a hand-grippable base to which an elongate accessing tube is connected which extends to a tip. Extending inwardly from the tip is a detection support region within which is formed a radiation transmissive window. Immediately spaced from and behind the window there is positioned a detecting crystal such as cadmium telluride which is retained in a crystal mount structure having an architecture designed for minimizing noise generation occasioned from microphonic (piezoelectric) phenomena and the like.
