A burned out bulb, a blocked eye piece, a dislodged mirror or your other eye is closed.
When only half of the field is illuminated in a microscope, it may be due to uneven lighting from the light source or improper adjustment of the mirror or condenser. Ensure the light source is evenly distributed across the field, adjust the mirror or condenser to center the light properly, and make sure the specimen is in focus to maximize illumination.
The field of view in a microscope is typically measured using a ruler or a stage micrometer slide that has a scale etched onto it. By calibrating the microscope with these reference tools, you can determine the size of the field of view at different magnifications.
This process is called calculating the field of view diameter on a microscope. It involves measuring the diameter of the field of view using a ruler and knowing the magnification of the objective lens to determine the actual size of objects viewed under the microscope.
Calculating the diameter of the field helps determine the field of view under the specific objective lens magnification you are using. This information is crucial for accurate measurements and observing the size, orientation, and movement of objects on the microscope slide. It also helps in understanding the scale of the objects being viewed.
You would need to move the slide to the right in order to bring the object from the left side to the center of the field of view under the microscope.

The field of view using a dissecting microscope is typically larger compared to that of a compound microscope, ranging from a few millimeters to centimeters depending on the specific model. The size can vary based on the magnification power of the lens being used.
In microscopy, the mechanical stage is a way to move the slide around on the stage. The field does not change as the mechanical stage is moved because of the mechanical contact between the specimen and the objective lens.
This process is called calculating the field of view diameter on a microscope. It involves measuring the diameter of the field of view using a ruler and knowing the magnification of the objective lens to determine the actual size of objects viewed under the microscope.
The changes in the field of view and the amount of light when going from one low to high power using the compound microscope is 40X for (LOW) And 100X for (High).

Antonie van Leeuwenhoek is credited with discovering protozoa in pond water using a microscope in the 17th century. His observations were groundbreaking in the field of microbiology and helped lay the foundation for our understanding of microorganisms.
To measure the length and width of a paramecium in microns using a 40x magnification microscope, you can use a calibrated eyepiece graticule or stage micrometer to determine the field of view in microns at that magnification. Then, you can measure the paramecium by counting the number of microns it spans across using the field of view as a reference. This will allow you to estimate the length and width of the paramecium in microns.
If you move the slide to the left using a microscope, the specimen will appear to move to the right in the field of view. This is because the movement of the slide in one direction causes the specimen to move in the opposite direction within the field of view of the microscope.
the problem may be, that your microscope it out of focus, i had that problem to, look at the screen itself, on the zoom bits, make sure they are clean, otherwise, adjust the distance away from the item, by using the turner on the side
