You should use the lowest value lens. It is the shortest one.
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.
To locate a specimen on a microscope, you typically start with the low-power objective lens, usually 4x or 10x. This magnification provides a broader field of view, making it easier to find the specimen. Once located, you can switch to a higher power objective lens for more detailed observation. Always ensure to use the coarse focus knob with low power and the fine focus knob with higher magnifications for clarity.
When observing a specimen under a microscope, you typically start with a low magnification objective, such as 4x or 10x, to locate and identify the targets of interest. Once you have identified the general area of interest, you can then switch to higher magnification objectives, such as 40x or 100x, for more detailed observation and analysis.

It would be 50x. To find the magnification, you just have to multiply the number eyepiece and the number objective. So for example, * A 10x eyepiece and a 40x objective would have a magnification of 400x * A 10x eyepiece and a 100x objective would have a magnification of 1,000x
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.

Try it any other way and you'll see. The scanning objective has the largest field of view, the greatest depth of field, and the greatest working distance. It is the most forgiving objective. It is the easiest to find the specimen and focus on it.
When viewing a specimen, you must always use the lower power objective lenses first. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.
The low-power objective lens (usually 4x) is always used first to locate an object on a microscope. This objective lens provides a wider field of view and a lower magnification, making it easier to find and center the specimen before moving to higher magnifications.

Always ensure to use the coarse focus knob with low power and the fine focus knob with higher magnifications for clarity.
Starting with a 4x objective allows for a larger field of view and greater depth of field, making it easier to locate and focus on the specimen. Higher power objectives have a smaller field of view and shallower depth of field, which can make it challenging to find and keep the specimen in focus.

Once you have identified the general area of interest, you can then switch to higher magnification objectives, such as 40x or 100x, for more detailed observation and analysis.
The objective used when observing a fresh specimen is typically a low-power objective lens, such as a 4x or 10x lens. This allows for a wider field of view and better visualization of the overall sample without the need for magnification.
The scanning power objective relates to the objective lens. Most microscopes provide two or more objective lenses to give a choice of magnification power. Some also include an oil immersion lens for even greater magnification.
Focusing a specimen under low power objective (LPO) allows you to find and center the specimen on the slide before moving to higher magnifications. This ensures that the sample is in the field of view and helps in adjusting the focus and moving to higher magnifications without losing sight of the specimen.
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.
