A thin-film optical device is formed on a substrate by atomic layer deposition. A mixing system provides a homogeneous gaseous mixture having a controllable ratio of first and second reactive gaseous materials. The first and second reactive gaseous materials each react with a third reactive gaseous material but do not react with each other. The homogeneous gaseous mixture is provided to a first inlet port, the third reactive gaseous material is provided to a second inlet port, and an inert gaseous material is provided to a third inlet port. The gas flows are directed through corresponding output channels of the delivery head toward the substrate. The mixing system is controlled to change the ratio of the first and second reactive gaseous materials as a function of time as the substrate is moved relative to the delivery head with an oscillating motion such that deposited layers have a varying composition.
