Adjusting the Condenser & Diaphragm

1. Using the condenser-adjustment knob (left of unit, under the stage), 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.

2. By changing the aperture (hole size) of the iris diaphragm, you can adjust the background brightness. Adjust the

aperture of the iris diaphragm using the iris adjustment slider located directly under the stage.

3. If you want to use a color filter, swivel the filter holder out, towards you. You can now place the desired color

filter into the circular opening. Slide the filter holder back to original position before observation.

Note: The filter holder is placed in from the factory in a manner in which it swings out and hits the arm of the

microscope (backwards). If this happens, simply grip the condenser assembly and rotate it. It may take a small

amount of force to rotate it, but after doing so, you will be able to swing the filter holder out towards the front of

the unit for easier operation.

If you have also purchased a camera for this unit, all you need to do is remove the eyepiece from the ocular tube

and slide the camera (with reduction lens installed) into the vacant tube.

1. Unlock the limit-stop on the rear stage (unscrew the lower bolt in the assembly).

2. Adjust the limit-stop to the desired maximum height.

3. Lock the stop-limit (screw in the bottom bolt in the assembly). This will allow you to limit the movement of the

stage from the bottom of the range up to the point that it is set at.
