The fine adjustment on a microscope is the smaller of the two knobs on the side. It is used after the coarse adjustment, which moves the platform up/down. It is mainly used to focus.
The course adjustment on a microscope is used to focus on the specimen initially. It is a larger adjustment that moves the stage up and down quickly to bring the specimen into view. Once the specimen is roughly in focus using the course adjustment, the fine adjustment knob is used to fine-tune the focus.
to focus on the specimen
The fine adjustment, the two little knobs on both sides of a compound microscope, is rotated to move the body tube down or the stage up in tiny distances to help you focus in HIGH power.The fine focus knob is geared with a different ratio than the coarse knob to "fine tune" your focus. It allows for tiny adjustments to the focus setting, rather than larger ones.
The coarse focus adjustment knob is used to move the objective lens closer to or further away from the specimen in large increments, allowing for quick focusing at a general level. This adjustment is typically used initially to bring the specimen into view before fine-tuning the focus with the fine focus knob.
To focus on a specimen using a microscope, you will typically use the coarse adjustment knob for initial focusing and the fine adjustment knob for precise focusing. The coarse adjustment knob moves the stage up and down quickly to bring the specimen into view, while the fine adjustment knob allows for small, precise adjustments to achieve a clear image.
it is used for final focusing.
After you adjust the coarse adjustment knob, the fine adjustment knob makes it sharper or clearer.

The fine adjustment knob on a microscope is typically located on one side of the base near the coarse adjustment knob. It is used to make precise focusing adjustments when viewing a specimen under high magnification.
You use the fine adjustment to focus in HIGH power with a compound microscpe.
There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.
The coarse adjustment on a microscope is used to initially focus the specimen by quickly moving the stage up or down. It is used to bring the specimen into view before fine-tuning the focus with the fine adjustment knob.
The fine-adjustment knob on a microscope is used to precisely focus the image by making small adjustments to the distance between the specimen and the objective lens. It allows for fine-tuning the focus of the microscope to get a clear and sharp image of the specimen.
You should always use the fine adjustment on a microscope when you are focusing on high-power magnifications, typically 400x and above. The fine adjustment allows for precise focusing, which is crucial for observing details without risking damage to the slide or the lens. It is also recommended to use the fine adjustment after initially focusing with the coarse adjustment to enhance clarity.
because it has many compound parts to the microscope ex. body tube, ocular lens,coarse adjustment(rough), and fine adjustment (sharp)
