Although there is no a “Cylindrical Detector” object in Non-Sequential, there are several workarounds to make it, since most objects may act like a detector (To make any objects a detector, choose "Object Is A Detector" from the Type tab of the Object Properties dialog box). Once the object is set to be a detector, the intensity detected will be displayed on the Shaded Model display, and on the text listing tab of the Detector Viewer window.

There is a Cylinder Pipe object in OpticStudio but it cannot be used as a detector because the curves of the object are modelled exactly within OS—the curves are not approximated by facets. Only objects which are faceted can be used as detectors. But there are some alternative object types that all have a faceted representation and so would work as a detector:

• You could create a cylinder pipe object and then export it as a STL file and use this new object as your detector. (See Export CAD files: The File Tab > Export Group > CAD Files). Then, in the object properties of the new object check “Object is a detector”.


• You could use a pair of toroidal surfaces (The Setup Tab > Editors Group (Setup Tab) > Non-sequential Component Editor > Non-sequential Geometry Objects > Toroidal Surface)  each of which would form half a cylinder.
