Azimuthal integration of scattered light intensity using a conical lens

Research output: Contribution to journalArticle


A simple optical scheme using a conical lens to perform azimuthal integration of light collected in a light scattering experiment is described. A substantial increase in the signal-to-noise ratio of the scattered light intensity is achieved. The scheme is particularly useful in nonequilibrium experiments such as spinodal decomposition, where the angular distribution of scattered light varies slowly in time and is peaked in the forward direction.
