The direction of the averaged molecular orientation as well as the order parameter in injection-moulded flat plates of liquid-crystalline polymer (Vectra A950, A530 and A130) were investigated by infra-red dichroism. The measurements were performed with a low-cost Fourier-transform infra-red reflectance microscope. Lateral and depth profiles, inclusive of three-dimensional imaging, of the molecular orientation were measured as a function of thickness of the fiat plate and injection speed
