  • Mounting Arrangements +


    Mount must be specified when ordering.

    A
     This is a "ring mount"; i.e., the silicon wafer is offered on its ring without output connectors. This infrequently used arrangement is available on special request.

    B
     Microdot connector on the rear of the can.

    C  BNC connector on the rear of the can.

    Dimensions given in millimeters. 

    For detectors 1500 or 2000 mm deep, add 1.5 mm to the Y dimension.
