A Bonse–Hart camera suitable for studying dilute and weakly scattering systems has been developed. The required level of reduction of the parasitic background scattering was realised by replacing channel‐cut crystals by a pair of polished and deeply etched parallel crystals. The performance of this ultra‐small‐angle X‐ray scattering instrument is illustrated by means of two examples: the microstructure of a short‐range attractive colloidal system; and the growth dynamics of soot particles in a diffusion flame. In addition, the feasibility of performing dynamic X‐ray scattering experiments is demonstrated.
