显微镜 (xiǎn wēi jìng): กล้องจุลทรรศน์

In biology class, the teacher had us observe onion epidermal cells with a microscope, and I saw a cell nucleus for the first time.

The doctor examined the patient's blood sample under a microscope and found an abnormal red blood cell count, suspecting anemia.

This microscope's magnification is insufficient; we can't see the bacterial flagella clearly. We need to switch to a more advanced one.

In the lab, she put a drop of pond water on a slide and placed it under the microscope, seeing many swimming microorganisms.
