* Allows the microscopist to see a complete section without grid bar interruption.
* Smooth edges.
* Excellent dull/shiny side discrimination.
* The thickness of a particular grid pattern depends on the size of the hole; the larger the hole, the thicker the grid, in order to give the grid better dimensional stability and stiffness. The thickness varies from 25 µm for the smallest hole to 50 µm for the thickest hole.
