Using Microscope

On the picture above

1. Pick up microscope with both hands. One in the base, another in the arm.
2. Rotate revolver until ‘click’ sound, so the objective with weakest magnification placed on the middle of objective stage (picture a). Set the mirror below until sunlight reflect into ocular (picture b).
3. Put object glass right on middle of object stage. Set until the gap between object glass and stage get close or almost contact (± 0.5 cm).
4. hile seeing the ocular, rotate the coarse adjustment knob to set the focus until object appear. Rotate the fine adjustment knob until object seen clearly. Shift the object if necessary.
5. Use bigger magnification if necessary. Rotate the revolver to change lens.

Note: for strong magnification (1000x) use immersion oil. Pick up the object glass and drop the immersion oil on the object. Put dawn again the object glass on microscope and rotate the adjustment knob until objective lens contact with immersion oil. Vision seen in microscope is opposite current with the object. If the object glass shifted to left, the vision will shifted to right, just the opposite If the object glass shifted to right, the vision will shifted to left.
