Focused grids offer the most effective guarantee of absorption of the scattered radiation, but require exact positioning during X-ray exposure.
This is not possible for all applications.
Therefore CAWO also offers parallel grids, which do not require such precision when centring but still produce good results when a relatively large film-focus distance is used.
