Parts of a Microscope
A microscope has several important parts that work together. The eyepiece is where you look through to see your specimen. Below that are the objective lenses which come in different powers (4x scanning, 10x low power, and 40x high power) to magnify objects at different levels.
To get your specimen in focus, use the coarse adjustment knob for quick focusing on scanning and low powers. For fine-tuning, especially on high power, use the fine adjustment knob to make your image crystal clear. Remember - only use fine focus on high power!
The stage holds your slides in place with clips, while the diaphragm controls how much light passes through your specimen. More light isn't always better - sometimes adjusting it helps see details more clearly.
Try This! Practice moving between different objective powers. Always start with the scanning power (4x) to find your specimen, then rotate to higher powers for more detail.
