Easy to Operate :
1.Low magnification Observing specimens must be observed with a low magnification lens first because the low magnification lens has a larger field of view.
(1) Firstly, place the specimen under the objective lens, and turn the coarse adjustment wheel to make the objective lens 0.5cm away from the specimen.
(2) Then observe through the eyepiece and rotate the coarse adjustment wheel. When an object appears in the field of view, rotate the fine adjustment wheel until a clear image is obtained in the field of view. Observe the specimen, determine and move the part that needs further observation to the center of the field of view, and prepare to observe with a high magnification lens.
2. High magnification
(1) When switching the lens, you need to observe from the side to avoid collision between the lens and the glass slide.
(2) Observe through the eyepiece, and adjust the brightness of the light to a suitable range. Turn the fine adjustment wheel slightly until a clear image can be seen.
