A method for making polymeric reflectors and parabolic reflectors in particular. The reflector is made by forming a series of layers (12, 14, 16, 18, and 20) that are progressively thinner with the final polymeric layer (20) being about one millimeter in thickness. The reflector is then coated with a reflective layer (22) by vapor deposition. To make aparabolic reflector, the layers are spun cast at a constant, preselected rate throughout the process, including during the curing of each layer. Layer formation is made in a controlled, particulate-free environment and additives can be used to increase stiffness, decrease weight, and reduce stresses during curing.
