How to use a microscope and Notes
      【Low-usage times】
(1) take place and the mirror: a microscope usually kept in the box or cabinet, took out from the cabinet, grasping his right-arm, boosting the left-hand seat, the microscope will be on his left shoulder in front of the stage of the experiment, the mirror Blocks away from the table and back-end 1-2 inches is appropriate for sitting operation.
(2) to light: the thumb and middle finger spin the mobile device (hand-held objective should not move) so low at times that mirror the Jingtai-hole light (when the rotation touch call-in voice heard, that objective has been at the tube axis Center). Open the aperture, the light-up, and mirrors to light in order to observe the left eye in the eyepiece (right eye open), while adjusting the direction of mirrors, until the vision of a bright light evenly so far.
(3) specimen slide place: take a specimen on the microscope slide on the stage, we have to make up coverslip side, must take anti-by-piece Spring caught pushing, and then rotating screw-up film, Will have to observe the site of the light to pass the middle of the hole.
(4) focal length adjustment: the left hand by crude anti-clockwise rotation regulator, Jingtai slow to make up ground samples from the lens of about 5 mm film, attention should be on the rise Jingtai, not observed in the eyepiece. Must be looked at the right side of the Jingtai up, so as not to rise too much, resulting in the film were shot or damage. Then, at the same time opened his eyes, his left eye in the eyepiece observation, the slow left-clockwise rotation of rough adjustment, so that the Jingtai slow decline until the emergence of a clear vision of the object so far.
If the object is not vision, adjustable push-piece to its center (note the move in the direction and vision glass object is moving in the direction opposite). If the vision of inappropriate brightness can be set off and landing light's location to open or closed to regulate the size of the aperture, if the adjustment in focal length, Jingtai decline over the work of the distance (> 5.40mm) did not see the object on the Failure of the operations should be re-operation, must not be impatient and blindly Jingtai up.
【High-use】
(1) good: he must at times of low under the observation of the site further to the center, at the same time object to adjust to the most clear, in order to carry out high-power microscope observation.
(2) rotating converters, high-power lens on the exchange, conversion at high-speed rotation to slow and observe from the side (to prevent high-power lens slide collision), such as high-power lens slide across on the low times of the focal length of the lens does not Transfer, should be re-operation.
(3) focal length adjustment: high-conversion well, with his left eye in the eyepiece on the observation, at this time is generally not very clear to see an object can be fine regulator of mobile anti-clockwise spiral around 0.5-1 circle, that is, The objects will be clear (not to use rough regulator!)
If the vision of inappropriate brightness can be set to be light and aperture adjustments need to be replaced if the glass samples, it is important to clockwise (not to turn the wrong direction) rotation allows Jingtai decline in crude-conditioning in order to remove the specimen slide.
Want as big so that it is necessary to make objects close to the lens, lens away from the eyepiece, like are smaller ... On the other hand ...

Notes microscope
Who must be a mirror when the arm holding his right hand, left hand up the seat position, not Extraction one hand, in order to avoid a collision or parts off to other places.
Helena release light light, the microscope can not be placed on the edge of the test-bed, so as not to fall Pengfan.
Maintain the cleanliness of a microscope, optical and lighting can only be part of the rub-clean paper, should not have blown the mouth with a cloth hand towels or rub, part of the machinery used to clean cloth.
Drop of water, alcohol or other drugs not to contact lenses and Jingtai, if the contamination should be immediately wipe.
Slide specimens to be placed at the light-central hole and can not take anti-slide, slide or Peng Huai Yahuai to prevent the objective lens.
At the same time, opened his eyes to cultivate the habit in order to observe the left eye vision and the right eye for graphics.
Do not remove the eyepiece at random in order to prevent dust from falling into the lens, not arbitrary demolition of a variety of parts to prevent damage.
After use, we must be able to recover back into the mirror box, the steps are: off-chip samples, spin rotation allows the camera to leave the light-hole, Jingtai decline, flat mirrors, optical-drop (but do not touch mirror ), The closure of the aperture, the push-back films, and covered with Choubu housing, test-bed back into the cabinet. Finally, fill out the registration form to use. (Note: vertical mirror normally be released, but sometimes as a result of set-ray did not mention due to a high degree, will decline in Jingtai Peng Huai aperture, so read here instead of horizontal ones)
