How to use â– How to use low magnification mirror
(1) Take the mirror and place it: The microscope is usually stored in the cabinet or box, taken out from the cabinet when it is used, the mirror arm is gripped by the right hand, the mirror holder is held by the left hand, and the microscope is placed on the test bench in front of the left shoulder of the mirror. The back end is 7 cm from the side of the table, which is convenient for sitting.
(2) Opposite light: Move the rotator with the thumb and middle finger (do not move the lens of the hand-held object), so that the low-power lens is aligned with the light-passing hole of the stage (when the rotation hears the click, the optical axis of the objective lens is aligned with the lens barrel) center). Open the aperture, raise the concentrator, and turn the mirror to the light source, observe it on the eyepiece with the left eye (open the right eye), and adjust the direction of the mirror until the light in the field of view is even and bright.
(3) Place the slide specimen: Take a specimen of the slide on the stage, make sure that the side of the cover slip is facing up, do not reverse it, clamp it with the spring clip of the pusher, and then rotate the spinner of the pusher. , adjust the part to be observed to the center of the light hole.
(4) Adjusting the focal length: Turn the coarse adjuster counterclockwise with your left hand, so that the stage slowly rises to about 5 mm away from the specimen. Note that when looking up the stage, do not observe it on the eyepiece. Be sure to look at the stage from the right side to avoid excessive rise, resulting in damage to the lens or specimen. Then, both eyes are opened at the same time, and the left eye is observed on the eyepiece, and the left hand slowly rotates the coarse adjuster clockwise, so that the stage is slowly lowered until a clear object appears in the field of view.
If the object is not in the center of the field of view, adjust the pusher to adjust it to the center (note that the direction of the moving slide is opposite to the direction in which the object is moving). If the brightness in the field of view is not suitable, it can be adjusted by the position of the lifting concentrator or the size of the opening and closing aperture. If the stage is lowered by more than the working distance (>5.40mm) when the focal length is adjusted, the object is not seen. If the operation fails, you should re-operate, and you must not blindly and blindly raise the stage.
â– How to use high power mirror
(1) Selecting the target: It is necessary to first adjust the part to be further observed under the low power microscope to the center, and adjust the object image to the clearest level in order to observe the high power microscope.
(2) Rotate the converter to change the high-power lens. When converting the high-power lens, the rotation speed should be slow and observe from the side (prevent the high-power lens from colliding the slide). If the high-power lens hits the slide, the focal length of the low-power lens is not Adjust it, it should be re-operated.
(3) Adjusting the focal length: After converting the high power microscope, observe it with the left eye on the eyepiece. At this time, you can usually see a less clear object, and the spiral of the fine adjuster can be moved counterclockwise by about 0.5-1 turn, ie Get a clear image (do not use a coarse regulator!)
If the brightness of the field of view is not suitable, it can be adjusted by the concentrator and aperture. If you need to change the slide specimen, you must turn the coarse adjuster clockwise (do not turn the wrong direction) to lower the stage to remove the slide specimen.
If you want to make the image bigger, you should make the objective lens close to the object. The eyepiece is far away from the objective lens. If it is smaller, the opposite is true...
Precautions â– When holding the mirror, it must be in the position of the right hand arm and the left hand holder. Do not pull it with one hand to avoid the parts falling off or colliding with other places.
â– Handle lightly. Do not place the microscope on the edge of the test bench. It should be placed 10cm away from the edge to avoid falling over.
â– Keep the microscope clean. The optical and illumination parts can only be wiped with a mirror paper. Do not wipe it with a hand or wipe it with a cloth. Wipe the mechanical part with a cloth.
â– Do not touch the lens or the lens with water droplets, alcohol or other medicines. If it is stained, wipe it off with lens tissue immediately.
â– When placing the slide specimen, align it with the center of the light-passing hole, and do not reverse the slide to prevent crushing the slide or touching the objective.
â– To develop a habit of keeping your eyes open while observing the field of view with your left eye and drawing with your right eye.
â– Do not remove the eyepiece at will, to prevent dust from falling into the objective lens, and do not arbitrarily disassemble various parts to prevent damage.
â– After use, it must be restored before being put back into the mirror box. The steps are: remove the specimen, turn the rotator to move the lens away from the light-passing hole, lower the mirror table, lay the mirror down, and lower the light collector (but do not touch the reflector) Mirror), close the aperture, push the ejector back, cover the silk cloth and cover, and put it back into the laboratory cabinet. Finally fill out the registration form. (Note: The mirror should normally be placed vertically, but sometimes the height of the concentrator is not raised, and the aperture will be damaged when the stage is lowered, so it is changed to flat)
