On which part of the compound light microscope are specimens placed for viewing?
Stage is where the specimen to be viewed is placed. A mechanical stage is used when working at higher magnifications where delicate movements of the specimen slide are required.
What term is used to describe the thickness of the specimen that can be in focus at a given time?
The depth of focus is the thickness of the specimen that remains in focus at a given magnification. Depth of focus decreases at higher magnifications.
When using a compound light microscope What is the most common reason for staining a specimen?
The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope. Cells may also be stained to highlight metabolic processes or to differentiate between live and dead cells in a sample.
What is the approximate diameter of the field of view when using the low power objective?
Diameter of field using low power objective lens = 1.8 mm, convert to micrometers. Diameter of field using high power objective lens = 0.5 mm, convert to micrometers.
