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.
What else can I help you with?
Which microscope knob do you not use on high power?
You do not use the coarse focus knob on high power because it can damage the slide and the objective lens of the microscope. Use only the fine focus knob to bring the specimen into sharp focus on high power.
Why should the course-adjustment knob on a microscope not be used with a high-power objective lens?
The course-adjustment knob moves the stage up and down quickly, and using it with a high-power objective can potentially damage the objective or slide due to a rapid change in focus. It is best to use the fine-adjustment knob when using a high-power lens for precise focusing.
If you use the coarse-adjustment knob to focus on an object with the high-power objective what problems will you encounter why?
Using the coarse-adjustment knob with the high-power objective can result in the objective lens getting too close to the slide, potentially damaging the lens or slide. This can also lead to the objective lens hitting the slide, causing a loss of focus and potential damage to both the lens and the slide.
How would you estimate the size of object viewed under high power objective lens 40 times if you were given the size of the field diameter when using low power objective lens 4 times?
You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.
Why should you only use the fine adjustment knob when you are using high power?
The fine adjustment knob should be used with high power magnification because it allows for smaller, more precise movements of the objective lens. This helps to prevent damage to the slide and objective lens, as well as minimize the risk of crashing the objective lens into the slide.
What does a high-power objective do on a microscope?
The high-power objective magnifies the image 4x.
What is the use of high power objective?
The high power objective increases the magnification of the specimen (it contributes to a further magnification). It magnify specimens at greater resolutions, which allows you to see fine details.
What is the usual magnifying power of the high power objective on your compound microscope?
The high power objective on a compound microscope typically has a magnifying power of 40x or 50x.
Which objective is longer on a microscope?
high power objective
What is High power objective?
The longest objective that is usually used the least. The opposite of a low power objective.
What is high power-objective?
The longest objective that is usually used the least. The opposite of a low power objective.
What is high power objective in a telescope?
The high power objective is used to zoom in a little bit more than the low power ob

Why is it important to use the fine adjustment knob when using the highest power objective lens?
So you do not crack the high power objective lens - this lens is very fragile and expensive.
Which microscope knob do you not use on high power?
You do not use the coarse focus knob on high power because it can damage the slide and the objective lens of the microscope. Use only the fine focus knob to bring the specimen into sharp focus on high power.
What is high power?
The longest objective that is usually used the least. The opposite of a low power objective.
What is high low objective in a microscope?
In microscopy, the high-low objective refers to the use of multiple objective lenses with varying magnifications, typically a high-power lens (e.g., 40x or 100x) and a low-power lens (e.g., 10x or 20x). The low-power objective is used for scanning and locating areas of interest on a specimen, while the high-power objective allows for detailed observation of specific structures. This combination enables efficient examination and detailed analysis of samples in biological and material sciences.
