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?
Oculars are generally 10x, so I assume you're talking of the 40x objective (10x40=400, how total magnification is derived). The most important rule is NEVER touch the coarse focus adjustment, only the fine; you run the risk of breaking the specimen or the objective if you mash the two together. Other things to consider- high light level, make sure koehler illumination is established and adjust your field aperture to eliminate refringence.
Why do we never use the coarse focus knop while the high power 40x lens in place?
We avoid using the coarse focus knob with the 40x lens because it can lead to a high risk of crashing the lens into the slide, potentially damaging both the slide and the objective lens. The coarse focus knob moves the stage significantly, which is suitable for lower magnifications, but at high power, even small movements can cause contact. Instead, the fine focus knob should be used to make precise adjustments for clear imaging.
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?
The coarse adjustment knob should never be used when viewing in high power with a compound microscope. When in high power, use the coarse adjustment (the knob smaller than the coarse adj.) to more accurately focus on the subject.
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 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 should you never use direct the coarse adjustment knob on high power?
Well, friend, using the coarse adjustment knob on high power can damage both the microscope and your slide. It's like trying to paint a delicate flower with a big brush - you need a gentle touch for the best results. Take your time, use the fine adjustment knob, and you'll see the beauty of your specimen clearly and without harm.
Why would you never use the coarse adjustment knob on high power?
The coarse adjustment knob may move the lens too far too fast and the slide may crack and/or the object be squashed. Using the fine adjustment lens will bring the object into focus much more accurately. In addition, the coarse adjustment knob adjusts in too great a quantity. The fine is less responsive so its easier to adjust at high magnification.
What are the microscope rules?
Some common microscope rules include always starting with the lowest magnification, focusing carefully using coarse and fine adjustment knobs, keeping the lenses clean, handling slides gently, and using the microscope in a well-lit area. Additionally, it's important to never force any parts, such as the stage or focusing mechanisms, and to always carry the microscope with two hands.
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 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.
Which two pieces from the microscope should you never touch?
is it you shouldn't touch chemicals with your hands
