When focusing with a microscope do you always focus toward the specimen?

No, when using a microscope, you should focus away from the specimen initially by moving the objective lens upward, then slowly bring it down towards the specimen to avoid damaging the lens or the specimen.


When viewing a specimen under the microscope you should always start with what?

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.


When viewing a specimen under the microscope you should always start with the?

low power objective lens to locate and focus on the specimen before moving to higher magnifications.


What should you do when viewing a specimen under highpower if you completely lose the focus?

If you completely lose focus while viewing a specimen under high power, you should first move the fine adjustment knob in both directions to try and regain focus. If that doesn't work, switch back to a lower magnification objective lens, refocus the specimen, and then switch back to the high power objective to try focusing again.


What kind of objective should be used in studying whole section of a specimen?

The objective lens used to study a whole section of a specimen should have a low magnification power (e.g. 4x or 10x) to provide a wide field of view and enable the entire section to be seen clearly. This helps in obtaining an overall understanding of the specimen's structure and context before moving to higher magnifications for detailed examination.

When focusing a specimen you should always start with the?

When focusing a specimen, you should always start with the lowest magnification objective lens, typically the scanning objective (4x or 10x). This allows for a broader field of view, making it easier to locate the specimen. Once the specimen is centered and in focus at low magnification, you can then switch to higher magnification lenses for more detailed observation. Always use the coarse focus knob first, followed by the fine focus knob for precision.

Why should you always begin focusing on a specimen with the 4x objective lens in place?

You should always begin focusing on a specimen with the 4x objective lens because it provides the widest field of view, allowing you to locate the specimen easily. This lower magnification also offers a greater depth of field, making it easier to find and center the specimen before switching to higher magnifications. Additionally, starting with the 4x lens minimizes the risk of crashing the objective lens into the slide, which can damage both the slide and the lens.


When focusing the microscope one should begin with which objective?

When focusing a microscope, one should begin with the lowest power objective, typically the scanning objective (4x or 10x). This allows for a broader field of view, making it easier to locate the specimen. Once the specimen is in focus at low power, one can then switch to higher power objectives for more detailed observation. Always use the coarse focus knob with low power and switch to fine focus at higher magnifications.


Which adjustment screw must be used when focusing the 40X objective?

The fine adjustment screw is used when focusing the 40X objective. The coarse adjustment screw should only be used with lower magnifications to bring the specimen into rough focus.


Why should you always move the objective lens away from the slide when your focusing the microscope?

Moving the objective lens away from the slide when focusing prevents the lens from accidentally coming into contact with the slide and potentially damaging both the lens and the specimen. It also helps in preventing the lens from scratching the slide, ensuring clear and accurate observations.


What focus adjustment should you use to focus on the specimen under the high power?

When focusing on a specimen under high power, you should use the fine adjustment knob. The coarse adjustment knob is typically used only under low power to prevent damage to the slide or objective lens. The fine adjustment allows for precise focusing, which is crucial at high magnifications to achieve a clear and sharp image of the specimen. Always ensure that you start with the lowest power objective before switching to high power for safety.

When you are focusing on a object in which order should the three objective lenses always be used?

When focusing on an object using a microscope, you should always start with the lowest power objective lens first (usually the scanning lens, 4x), then move to the medium power lens (10x), and finally to the highest power lens (40x or higher). This order helps prevent damage to the slide and the lens, and makes it easier to locate and focus on the specimen. Always ensure the stage is lowered when switching to higher magnifications to avoid crashing the objective into the slide.

What particular objective should be use when a general view of the specimen is to be used?

When starting a microscopic study,always examine under LPO first.Move the slide and get a good general view of the specimen.
