Center the slide on the stage. Looking from the side, decrease the distance between the slide and the objective lens until the lens comes to a stop. Looking throught the ocukar lens(es), use the coarse-adjustment knob to increase the distance between the slide and the lens until the object comes into view.
The high power objective has a shorter focal length and narrower field of view compared to the low power objective. This can cause the specimen to move out of the field of view when switching from low to high power, especially if it was not centered properly. Adjusting the mechanical stage to re-center the specimen or refocusing the microscope may help bring the specimen back into view on high power.
Low power on a microscope refers to lower magnification levels, allowing you to see a larger area of the specimen with less detail. High power, on the other hand, refers to higher magnification levels that provide a more detailed view of a smaller area of the specimen.
Centering a specimen on low power ensures that it is within the field of view and makes it easier to locate and focus on at high power. If a specimen is not centered on low power, it may be difficult to find and focus on when switching to high power, leading to potential damage to the specimen or microscope lenses. Additionally, centering the specimen helps to achieve the best image quality and clarity at high magnification.
To locate a specimen on a microscope, the low power objective lens is typically used, often a 4x or 10x magnification. This lens provides a wider field of view, making it easier to scan the slide and find the specimen. Once located, higher power objective lenses can be used for more detailed observation.
No, switching from low power to high power magnifies the image but does not change its position. The position of the image remains the same as long as the slide or specimen is not moved.
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
It means you have a good microscope.

The low power magnification of a microscope typically ranges from 10x to 40x. This level of magnification is used for initial scanning of a specimen and provides a wide field of view.
To view a specimen under high power on a microscope, first ensure the specimen is properly mounted on a slide and in focus under low magnification. Then, increase the magnification to high power, typically 400x or higher, using the lens adjustment knob without contacting the slide. Finally, fine-tune the focus using the fine focus knob to get a clear view of the specimen at high magnification.

First put the specimen into focus using a low power lens, then switch to a higher power lens if needed.
Low power on a microscope refers to lower magnification levels, allowing you to see a larger area of the specimen with less detail. High power, on the other hand, refers to higher magnification levels that provide a more detailed view of a smaller area of the specimen.
The coarse focus knob is used to bring the specimen into general focus when using the low-power lens on a microscope. This knob moves the stage up and down to adjust the distance between the lens and the specimen, allowing for rough focusing.
The lens used to locate a specimen on a microscope is typically the lowest magnification lens, known as the scanning lens or low power objective. This lens provides a wide field of view, making it easier to find and center the specimen before switching to higher magnification lenses for detailed viewing.
Because it is too hard to find a specimen on high power. Easier to find them and focus them on low power and then increase the magnification and fine-tune the focus to get a better, closer look.
