A small‐angle light scattering (SALS) instrument with a high resolution at low angles and a high signal‐to‐noise ratio has been developed. Both a wide dynamic range and a wide scattering vector range are achieved using a two‐dimensional array of complementary metal oxide semiconductor image sensors. These instrument characteristics have enabled us to obtain high‐quality light scattering data from soft matter systems. This setup is especially well suited to studies of systems with a weak scattering power and/or a time‐dependent structure evolution in a wide spatial range from submicrometre to submillimetre. An application of this instrument to a polyelectrolyte blend and an extremely thin blend film are reported.
