Mix a large drop of honey with a drop of water on a microscope slide and apply a coverslip. Test articles are placed in a Petri dish where the surface is inoculated and covered with a glass coverslip. Cells were distributed to plates with 25-mm poly-L-lysine-coated coverslips at a …
The main function of the cover slip is to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. This is necessary because high-resolution microscopes have a very narrow region within which they focus. The cover glass often has several other functions.
The purpose of coverslipping is: protect tissues from scratching & being removed from the slide. Keep tissue as well as stain from drying out, improve the refractive index, prtect stain from fading.

This concept is illustrated in Figure 3, which presents the calculated maximum intensity in the image of a point object versus the deviation of the coverslip thickness, from the ideal value of 0.17 millimeters, as a function of objective numerical aperture.
Oil immersion can generally only be used on rigidly mounted specimens otherwise the surface tension of the oil can move the coverslip and so move the sample underneath. This can also happen on inverted microscopes because the coverslip is below the slide.

3. Drop one or two drops of mounting medium onto the coverslip. 4. Lower a slide carefully onto the long edge of the coverslip and allow it to cover the slide, spreading the mounting medium evenly and without air bubbles. If air bubbles form under the leading edge of the cover slip, move the cover slip up slightly and remove the air bubbles. 5.
