A higher power objective lens in a microscope is used when greater magnification is needed to study an object.
The higher power objective lens has a shorter focal length and needs to be closer to the object being studied. It has a smaller aperture (lens diameter) so it has a narrower field of vision and may require more light to be useful. This means that it is more difficult to find and center the item being studied under the lens and it is harder to focus the lens on the object.

Which part of a microscope should be used with the low power objective but not with the high power objective?
Coarse Adjustment

What is high objective?

When do you use the high power objective?
The high power objective on a microscope is used anytime you need to achieve greater detail and magnification, and is often used when identifying cells. The high power objective is generally not used in teaching/learning labs as it is usually an oil immersion lens. Using oil means greater cleaning & care is required.
When should the high power objective be used?
When a very close view of the specimen is necessary. You can focus in on one part of the specimen.
What is the function of the high power objective on a microscope?
The high power objective on a microscope increases the magnification of the specimen, which allows you to see more detail. It allows you to see a close up of only a small area of the specimen being viewed.
What is objective power?
The longest objective that is usually used the least. The opposite of a low power objective.
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.
Which objective would be better to use when using a scanning slide?
Might add extra, but i really hope this helps! scanning objective - for locating the specimen on the slide (= low power objective) high power objective - magnifies the specimen to provide a detailed image coarse adjustment - used to focus the image when using low power diaphragm - used to adjust the amount of light passing through the specimen revolving nosepiece - holds the three objective lenses - it can be rotated to change the objective in use arm - holds the stage and the lens system - can be used to tilt the microscope (but not advised) substaGe lamp - provides a uniform illumination (more reliable than daylight !!)
