because it allows you to find the part of the slide you want to see, then you can zoom in by changing focus to see the frame in greater detail. if you don't start in low power it is extremely difficult to move around the slide
Do not allow the high power objective to tough the lenses
Scanning objective
When viewing a specimen under the microscope, you should always start with the lowest magnification objective lens. This allows you to locate and focus on the specimen before moving to higher magnifications for a closer look.
Yes, it is recommended to store a microscope with the objective lens in place to prevent dust or debris from entering the lens threads and affecting the performance of the microscope. Additionally, storing the objective in place helps maintain the alignment and calibration of the microscope for accurate observations.
When working with a microscope you should always take procauctions but one question I am asked a lot is When working with a microscope do you open or close the diaphram when working with the medium- and high-power objective nobs? The answer is you keep it open if you don't you won't be abler to see any thing.
so the objective lens will not touch the slide.
10x
low power objective lens to locate and focus on the specimen before moving to higher magnifications.
When focusing the microscope downward, you take the chance of damaging the expensive objective lens by crushing the slide trying to get it.
A microscope should be stored with the lowest-power objective lens in place to prevent damage to the higher-power lenses. It is recommended to keep the 4x or 10x objective lens in place for storage as they are less delicate than the higher magnification lenses.
When using a microscope, always start with the lowest magnification objective and gradually increase the magnification to avoid damaging the slides. Additionally, remember to always use both hands when handling the microscope to ensure stability and prevent accidents.
The objective lens with the lowest magnification, usually 4x. Be sure to clean all the lens with lens paper before putting the microscope away.
