Adjusting the Condenser & Diaphragm

1. Using the condenser-adjustment knob, you can change the distance between the light condenser and the stage.

This allows you to control the concentration of the light hitting your slide.

the unit for easier operation.

counter-clockwise to vary the focal length.
