The substage condenser fits in a depression in the stage. Also in this depression is the graduated, rotating stage.
Four lenses stack within the condenser body. All elements are plano-convex lenses, with the flat surface facing up (toward the sample). The top plate is flat to accommodate the rotating stage.
