First focus the microscope on the lowest objective using first the coarse djustment knob and then the fine adjustment knob. Once you have it in focus, move on and do the same for the next highest objective. Continue this process until you reach the highest objective and focus it in the same fashion.
Course Focus Knob- low Fine Focus Knob- high -MC
You use the fine adjustment to focus in HIGH power with a compound microscpe.
It can burn your eye.
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
rotated to move the body tube down or the stage up in tiny distances to help you focus in HIGH power.
The fine focus can move the stage up and down in tiny distances to help you focus in high-power.
Course Focus Knob- low Fine Focus Knob- high -MC
Once the object is in focus with lowest power, it should also be almost in focus with the higher power.
You use the fine adjustment to focus in HIGH power with a compound microscpe.
using the course adjustment to focus the specimen under high power
It can burn your eye.
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 high power objective in a microscope is the largest lens in the microscope.
It means you have a good microscope.
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
The fine focus knob is used to bring an object into fine focus, while the course focus knob is used to bring an object into approximate focus. The course focus knob should only be used on the low-power and scanning objectives of the light microscope. Using it on the high power microscope is okay, but you should be very careful. It is no recommended to use the course adjustment knob on the oil-emersion objective as it is so close to the stage and could lead to a potential break in the slide. Fine focus adjustment knob is useful to bring out the fine details in the specimen on your slide. Can be used on any of the objectives, but most receptive on the high-power and oil-emersion objectives.
