    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.

    T      Microdot on the side of the can; without adjustable screws. (Open back.)

    Dimensions are given in millimeters.
