What part of the microscope should you used to focus the image when using high power objective lens?
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.
Why should you never turn the coarse objective knob downward?
Turning the coarse objective knob downward can cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It is best to always start with the coarse knob in the upward position to prevent any accidental collisions.
Proper use of microscope in 400 magnification?
To use a microscope at 400x magnification, start by placing the slide on the stage and securing it with the stage clips. Use the coarse focus knob to bring the specimen into view, then fine-tune the focus using the fine focus knob. Adjust the light intensity for optimal visibility, and remember to always handle the microscope with care to avoid damaging the lenses or stage.
Why should you never point a microscopes mirror directly at the sun?
Pointing a microscope mirror directly at the sun can cause intense light to be focused into the microscope, leading to potential injury or damage to the microscope due to excessive heat or light intensity. This can cause the microscope's optics to overheat and potentially damage the lenses or cause a fire hazard. It's important to avoid pointing any optical instrument towards the sun to prevent accidents.

Which focusing knob do you never use under high power?
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.
Why should you never use the coarse adjustment knob on high power for a microscope?
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.
Why should you never use direct the coarse adjustment knob on high power?
Using the coarse adjustment knob on high power can cause the objective lens to hit the slide, potentially shattering both the slide and the lens. It can also damage the specimen and disrupt the focus, leading to blurry images.
Why should you never turn the coarse objective knob downward?
Turning the coarse objective knob downward can cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It is best to always start with the coarse knob in the upward position to prevent any accidental collisions.
Why shoukld you never use the coarse adjustment knob on high power?
Using the coarse adjustment knob on high power may cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It can also lead to misalignment of the optics, resulting in blurry images and potential damage to the microscope.
Why should you never us the coarse adjustment knob on high power?
Because the movement is too large and you can break the slide of you turn it the wrong way.
Why should you never use the coarse adjustment on higher power?
Using the coarse adjustment on higher power can risk damaging the lens or the slide because the distance between the lens and the slide is very small. It can also cause the objective lens to hit and break the coverslip or slide. Finer adjustments should be made with the fine adjustment knob when using higher magnifications to prevent this.
Why would you never use the coarse adjustment knob on high power?
Using the coarse adjustment knob on high power can potentially cause damage to both the microscope and the slide. High power magnification requires a more delicate touch to focus precisely, and the coarse adjustment knob moves the stage too quickly for fine adjustments at this level. It is better to use the fine adjustment knob on high power for accurate focusing.
Why should you never use a course adjustment knob on High power?
Using the course adjustment knob on high power can cause the microscope to move too quickly, potentially damaging the specimen or the objective lens. It is better to use the fine adjustment knob on high power for precise focusing.
Why should you never rack downwards with the coarse focusing while you are looking down the microscope?
Racking downwards with the coarse focusing while looking down the microscope can cause the objective lens to crash into the slide, potentially damaging both the lens and the specimen. It is advisable to always rack the focusing knob upwards to bring the specimen into view slowly and avoid any potential collisions.
Which two pieces from the microscope should you never touch?
You should never touch the objective lenses or the eyepiece of a microscope with your fingers. These components are delicate and any smudges or dirt can affect the quality of the images.
