The way the word 'flatness' is used, when discussing glass bottom dishes, there are two definitions of 'flatness'.

In the first place, there is the flatness of the glass coverslip bottom of the dish, when we talk about the glass coverslip being positioned in the dish as such, that it is absolutely horizontal on - and flush with, the warming stage.

Glass coverslip horizontal:
Positioned flat or horizontal means, that the light of the microscope passes the glass bottom orthogonally (very important) and that your cells stay in focus, when you move the stage, to another position (E.g. but not limited too: Time Laps Microscopy).

Glass coverslip 'flush', with the stage:
When the glass coverslip is flush with the stage, it means that there is no air-buffer, between the glass and the warming stage. The WillCo-dish® design, was - and is, the first dish to have this exceptional design. This feature too is very important, because it ensures an even distribution of the heat, from the warming stage to the media/liquid, inside the dish. All cells will be evenly heated, which is essential for the well being of your precious cells and the success of your work!

Note: If this is not the case, if there is an air-buffer between the warming stage and the bottom of the glass coverslip, an uneven distribution of the temperature to your cells, will shorten the life of your cells and dramatically influence the results of your work.

Coverslip roughness:
Secondly, when discussing 'flatness' of the glass coverslip, we mean the surface flatness (ar) or roughness of the surface of the glass. We offer two specifications; surface flatness ar 0.01 mm. (standard) and ar 0.005 mm. (This 0.005 mm. flatness, is specially selected glass, as is thickness 170 micron glass +/- 5 micron).
