THE SWIFT STAGE CONDENSER
The stage condenser is the standard form offered by Swift. Its purpose is provide concentrated bright light. It attaches to one of the two holes on the slide-holding bar on the mechanical stage(above, right), or alternatively, to the hole on either side of the limb(above, left). It was usually used to illuminate opaque objects such as would be held by a stage forceps as seen here above on the right.
