The invention concerns a combination of a microscope with a measurement device, in particular a diagnostic device, that is usable during an operation on or examination of a specimen performed with the microscope. Each of the first direction pixel lines includes a plurality of pixels. When the voltage is inadequate, then an alternate power source is automatically connected. A diffractive region of a multifocal insert of the present invention can be positioned to be in optical communication with one or more optical regions of a host lens to provide a combined desired optical power in one or more vision zones. In stopping a person or animal the tendrils will deliver a marking package, a shocking package or a snare package to mark, shock or snare the target.
