You use the low power objective lens first to get your sample centered in the field of view.

What is the power of the low power objective lens?
The low power objective lens helps to first fine the specimen or object being viewed, and to focus the microscope. Once the lens power becomes higher it is much harder to focus the microscope and find the desired object of viewing.
What is objective power?
The longest objective that is usually used the least. The opposite of a low power objective.
What is the name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?
I assume you would use the fine adjustment knob for high power objectives.
When focusing a specimen you should always start with which objective?

What is the BEST procedure for focusing a compound light microscope?
Begin by using the lowest power objective lens and then switching to the next highest power lens.
Which objective lens should you begin with?
The low power or lowest power objective
What is lpo and hpo?
LPO or Low- Power Objective is the smallest objective while HPO or High-Power Objective is the lowest objective.
What is a lower power objective?
The lower power objective is the lens on the microscope that gives you the lowest magnification. The exact magnification is 40x
Why Low power objective before High Power objective?
The low power objective is used first for two reasons: First, focusing the low power objective will insure that the other objectives will be at the proper height. Smashing a slide with an objective can damage the objective. Second, you can see a greater area with the low powered objective. This allows you to easily locate an object of interest, center it in frame and then zoom in on it.
When you put away a compound microscope what power should the objective lens be set at?
lowest power, i think 40x
When using a compound light microscope and focusing should the lowest power lens should be used?
yes it should.
When looking at a specimen for the fir ts time under a microscope do you view with high power objective or lowest objective fir ts?
first view with low power then gradually increase the power. hope it helped you!
What is the total magnification of the swift compound microscope when viewing an image under the lowest power objective?
50x
What is a scanning objective?
What is the function of the scanning objective on the microscope? What is the function of the scanning objective on the microscope? What is the function of the scanning objective on the microscope?
Which objective lens should always be in place when beginning to use the microscope and when putting it away?
The objective lens with the lowest magnification, usually 4x. Be sure to clean all the lens with lens paper before putting the microscope away.
