It will bring an object into focus..
Focusing a microscope upward on a slide can potentially crack the slide if too much pressure is applied. It is important to handle the focusing knob gently and avoid forcing the microscope objective lens against the slide to prevent damage.
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.
upward
When using a microscope, it is generally recommended to avoid focusing too far upward because this can cause the objective lens to hit the slide or specimen, potentially damaging both. It is also important to focus upward cautiously to prevent overshooting and losing focus on the specimen.
Focusing the microscope upward is better because it allows for easier manipulation of the fine focus knob, which typically moves the stage closer to the objective lens. This minimizes the risk of crashing the objective lens into the slide, which can damage both the lens and the slide. Additionally, focusing upward helps prevent accidental contact between the objective lens and the specimen, reducing the chances of smudging or contaminating the lens.
The coarse adjustment is used to focus in on the specimen. It accomplishes this by moving the stage or the upper part of the microscope.

To bring an object into focus on a microscope, you should start by placing the specimen on the stage and selecting the lowest magnification lens. Next, use the coarse focus knob to move the microscope stage upward until the object is visible, then use the fine focus knob to sharpen the image.
There is usually a tiltable mirror underneath where the specimen is placed, A small lamp shines on the mirror and the beam is directed upwards. In some microscopes an upward shining lamp takes the place of a mirror.
The mirror on a microscope reflects light onto the specimen being observed. By adjusting the mirror, you can control the amount of light that passes through the specimen, allowing for clearer visibility and better image quality.
When you move the slide down under the microscope, the specimen on the slide will appear to move upward in the field of view. This is due to the way light rays bend as they pass through the lens system of the microscope, resulting in the specimen appearing to move in the opposite direction as the slide.
