Throughout the years, many types of Neutron Double Converging Collimators have been produced by JJ X-Ray. As with our Radial Collimators, they include intermediate collimation systems over larger angular ranges and finer collimation systems over smaller angular ranges.
Especially with our larger designs, limiting the total system weight has been at the center of our attention.
