Focusing:

To achieve the best focus with your microscope, not only can you make adjustments with the

focus adjustment knobs, but you can also adjust the left diopter ring as well as the interpupillary

distance between the eyepieces. To achieve sharpest focus:

1. Rotate the objective turret (5) to the 2x position . (Always begin by viewing a specimen at low

power, then switch to high power when needed).

2. Turn the focus adjustment knob (11) until the specimen comes into focus. If there is not

enough travel in the focuser mechanism to reach focus, it may be necessary to loosen the

pillar stand locking bolt (12) and slightly raise or lower the entire binocular head assembly

until the image becomes sharp.

3. Next, while looking through the eyepieces, adjust the interpupillary distance by sliding both

eyepieces side to side until the whole field of view can be observed through both eyes at the

same time.

4. Finally, close your right eye and turn the left eyepiece diopter ring until the image is in sharp

focus through the eyepiece.

If higher power is desired, rotate the objective turret (5) to the 4x position and readjust the focus

knobs (11) until the specimen comes into focus.
