use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
Which of the following is a correct procedure for the operation of a microscope? First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
the diameter of the high power field microscope is 500 micrometers
the high power lens uses a lot of light scorce so it could burn your eyes
The Dissecting Light Microscope range of magnification is 20x to 80x. The Compound Light Microscope ranges from 40x to 1000x -40x Scanning -100x Low Power -400x High Power -1000x Oil Immersion
You do not use the coarse focus knob on high power because it can damage the slide and the objective lens of the microscope. Use only the fine focus knob to bring the specimen into sharp focus on high power.
For low power you can use the coarse adjustment and fine adjustment for high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
You should avoid using the coarse focusing knob under high power magnification as it moves the microscope stage too quickly, making it difficult to focus accurately. It is best to only use the fine focusing knob to make precise adjustments when working with high power objectives.

The coarse focus knob should be used with the low power objective but not with the high power objective. The point of using the coarse focus knob is to bring the specimen into general focus before fine-tuning with the high power objective, which requires more precise adjustments.
The fine adjustment knob is typically used to focus when using high power magnification on a microscope. It allows for precision adjustments to fine-tune the focus of the specimen being observed.
First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
Using the coarse adjustment knob on high power can potentially damage the microscope or the slide being observed due to the high magnification and close proximity of the objective lens to the slide. It is better to make coarse adjustments on low power to avoid hitting the objective lens against the slide.
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.
Start with the lowest power objective lens in place. Adjust the coarse focus knob to bring the specimen into rough focus. Switch to the high power objective lens and fine-tune the focus using the fine focus knob. Adjust the condenser to optimize the illumination for high power viewing.
When using a microscope under high power, you typically start by locating the specimen using the coarse adjustment knob on low power before switching to high power for a more detailed view. Under high power, you may need to use the fine adjustment knob more delicately to focus due to the increased magnification. Additionally, the field of view is smaller under high power compared to low power.
