Abstract
A surgical probe apparatus incorporates a probe structure with a handle component and forward crystal mount wherein a cadmium-telluride crystal is rigidly mounted against movement. A cup-shaped window assembly is provided having an internal cylindrical tungsten shield which extends forwardly from the front face of the crystal to define an air gap as well as to support an aluminum window. The window assembly is threadably mounted upon the handle at a transition region forming an outwardly extending ramp. This ramp is used in conjunction with a polymeric retainer component with legs containing dog structures which hold a cylindrical tungsten collimator in biased position against the window when attached.
