The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

The design of a grating usually involves considerations such as the material, the number of grooves per millimeter, the depth of the grooves, and the angle of incidence. In the case of 19w2% grating, the choice of material is critical. Common materials used for fabricating gratings include glass, quartz, and specialized polymers, each chosen based on the specific application. For ultraviolet applications, for instance, materials that absorb less in the UV range are preferred.
