4. 6V20W halogen lamp with adjustable brightness.
5. The trinocular lens tube can be switched free for normal observation, and it can perform 100 percent light-transmission photography with a unique anti-mold system.
operacija metodas
one. Take mirror and install
1. Hold the mirror arm with your right hand and drag the mirror base with your left hand.
2. Place the microscope about 7 cm away from the edge of the experimental table, slightly to the left, and install the eyepiece and objective lens.
3. Pasukite the konverteris to lygiavimas the low-magnification objektyvas lens with the light hole (the distance between the front end of the objective lens and the stage should be keptas 5 to 10 mm).
4. Align a larger aperture with the light hole, look at the eyepiece with one eye, open the other eye, turn the reflector, so that the light is reflected into the lens barrel through the light hole. You can see the white light through the okuliare roundular field of view.
3. Stebėjimas
5. Put the slide specimen to be observed on the stage, and press it with a pressure clamp, and the specimen should be facing the center of the light hole.
6. Pasukite the coarse quasi-focus screw to lower the lens barrel slow till the objective lens is close to the slide specimen (the eyes must look at the objective lens at this time, and the experimenter's eyes should look between the objective lens and the specimen to avoid collision between the objective lens and the specimen ).
7. Look inside the eyepiece with one eye, and at the same time turn the coarse focusing screw counterclockwise to make the lens barrel rise slowly until the object can be seen clearly. Then turn the fine focusing screw slightly to make the seen object clearer.
4. Wipe and close the lens
8. If need, wipe the okuliaras with the lens cleaning paper next to it, and put it back in place.
