An optical emitter assembly is described in which one or more optical devices each having an emitting aperture at a surface thereof can be mounted on a carrier such that the plane of the emitting apertures with respect to a well defined reference plane can be precisely controlled. This enables additional optical elements to be precisely axially and lateralty positioned with respect to the centre of the emitting apertures, even when there are plural optical devices of differing thicknesses. The assembly may comprise a surface-emitting optical device having an emission surface providing an optical output aperture; a carrier having first and second opposing surfaces, the first surface being a reference surface on which the optical device is mounted by its emission surface and the second surface being a back surface, the carrier having an aperture extending between the reference and back surfaces, the optical device being positioned on the reference surface such that its optical output aperture is in overlying relation with the carrier aperture to direct optical radiation therethrough.
