The general term is 'stain' of which there are several chemicals that can be used, depending on the specimen.
When a visible chemical haze is in the atmosphere it can be called a toxic cloud or nuclear fallout. This depends on the type of chemical that has been disbursed into the air.
The amount of specimen visible on a microscope is referred to as the field of view. This refers to the diameter of the circular area that is visible when looking through the microscope. The field of view may vary depending on the magnification level of the microscope lens.
A common chemical used to make specimens visible under a microscope is a stain, such as hematoxylin and eosin (H&E) stain. Stains are designed to highlight specific structures or components of the specimen by adding color contrast.
Chemicals such as dyes, stains, or fixatives are commonly used in specimen preparation to make them more visible under a microscope. Dyes bind to specific cellular components, stains highlight certain structures, and fixatives preserve the specimen's morphology for observation.

The term used to describe how much of an object or specimen you can see when looking down a microscope is called the "field of view." It refers to the visible area that can be seen through the microscope lens at a given magnification. The field of view decreases as magnification increases, meaning that at higher magnifications, you see less of the specimen.
When a microscope image is clear and sharp, it is referred to as being in "focus." Achieving focus involves adjusting the microscope's lenses and stage to ensure that the specimen is adequately magnified and details are visible. A well-focused image allows for better observation and analysis of the specimen's features.
The cover over the specimen on a microscope is called a microscope slide cover slip. It protects the specimen from dust and damage and helps to maintain the specimen in place while observing it under the microscope.
