You should first focus the slide on low power before you switch it to high power because it is easier to find the specimen on the slide. When you switch to a higher power, the field of view gets zoomed in.
Before switching to high power, the specimen must be in focus and positioned in the center of the field of view under low power magnification. Additionally, the light source should be properly adjusted to provide clear illumination of the specimen at high power.
The coarse focus knob should be used with the low power objective but not with the high power objective. The point of using the coarse focus knob is to bring the specimen into general focus before fine-tuning with the high power objective, which requires more precise adjustments.

prevent its disappearance due to the decrease in the field of viewTo do just that... center the object, because when the magnification is increased, the lens zooms in on the center, cutting out the perifery.
Because high power takes up a much smaller area, and you may not be able to find the specimen if it's off to one side. C:
Fine focus
Centering the image on a microscope before switching to a higher power ensures that the object of interest stays in the field of view. This helps maintain focus and prevents the risk of losing sight of the specimen when magnifying it further.
You should typically start with the lowest power lens (usually 4x or 10x) on a microscope to locate and focus on your specimen. This allows you to have a wider field of view and better control over the focusing before switching to higher power lenses for more magnification.
Centering the specimen before switching to high power on a microscope helps ensure that the area you want to observe is in focus and at the center of the field of view. This is important because high power magnification has a narrower field of view and lower depth of field, making it more challenging to locate and focus on the specimen if it is not first centered.
You should never lower the stage in a microscope before switching to high power because doing so can cause the objective lens to come into contact with the slide, potentially damaging both the lens and the slide. This can lead to scratches on the lens or breakage of the slide, compromising your samples. Additionally, maintaining a proper working distance helps ensure clear and focused images at higher magnifications. Always adjust the focus from low power before switching to high power.

WHY IS IT IMPORTANT THAT THE IMAGE IS CENTERED IN THE FIELD OF VIEW BEFORE SWITCHING TO A HIGHER POWER
Yes, when using a compound light microscope, it is recommended to start with the lowest power lens (usually 4x or 10x) to locate and center the specimen before switching to higher magnifications. This helps in getting a broader view and making it easier to focus accurately at higher magnifications.
Centering the specimen before switching to high power helps ensure that you are viewing the area of interest in focus. It helps prevent the objective lens from hitting the slide, which can damage both the lens and the specimen. Additionally, centering the specimen can improve the image quality by reducing glare and shadowing.
The coarse focus knob should be used with the low power objective but not with the high power objective. The point of using the coarse focus knob is to bring the specimen into general focus before fine-tuning with the high power objective, which requires more precise adjustments.
