Coverslips:
This smaller sheet of glass, called a cover slip or cover glass, is usually between 18 and 25 mm on a side. The cover glass serves two purposes: (1) it protects the microscope's objective lens from contacting the specimen, and (2) it creates an even thickness (in wet mounts) for viewing
In a wet mount, a drop of water is used to suspend the specimen between the slide and cover slip. Place a sample on the slide. Using a pipette, place a drop of water on the specimen. Then place on edge of the cover slip over the sample and carefully lower the cover slip into place using a toothpick or equivalent.
The standard thickness for cover glasses is 0.17 millimeters, which is designated as a number 1½ cover glass.
To use an oil immersion lens, first focus on the area of specimen to be observed with the high dry (400x) lens. Place a drop of immersion oil on the cover slip over that area, and very carefully swing the oil immersion lens into place. ... When in focus the lens nearly touches the cover slip
It protects the microscope and prevents the slide from drying out when it's being examined. The coverslip is lowered gently onto the specimen using a mounted needle . It is important that no air bubbles are trapped underneath. Most cells are colourless.
