You use the coarse adjustment knob first to find your specimen because it allows for significant movement of the stage or objective lens, making it easier to quickly locate the specimen under low magnification. Once the specimen is roughly in focus, you can then use the fine adjustment knob for precise focusing, ensuring a clear and detailed view.
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.
You should find the 'adjustment knob'.

You should always begin using a microscope with a lower power objective to locate and focus on your specimen more easily. Low power objectives provide a wider field of view, making it simpler to find the area of interest. Additionally, starting with lower magnification minimizes the risk of crashing the objective lens into the slide, which can damage both the slide and the microscope. Once the specimen is in focus, you can then switch to a higher power objective for detailed observation.

The course adjustment knob raises and lowers the stage of the microscope. This knob is mainly used on the scanning and low power knob to simply find the specimen. When trying to focus directly, use the fine adjustment knob.
Zoom all the way out on the coarse and fine adjustments.. Find it using coarse adjustment zoomed out and slowly zoom in then use find adjustment to make it clear

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.

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.
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.
that is a terrible idea considering when they examine the specimen they will find the bleach and you may be taken prison for tampering with a specimen....
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.
bactirea and stuff
find it of coarse. but no you can find them on the internet. go to ebay or craigslist and you can find one.
