Abstract
On account of their leight weight and other physical properties, plastic composite materials are ideal substrate materials for small and medium-sized mirrors. Coating these with PVD poses a problem since such plastics have only limited temperature resistance. Best results are found with a multilayer system based on a 300 micron thick plasma sprayed coating made of nickel and aluminium with a 200 micron electroless nickel on top. After mechanical finishing, the actual reflective layer is finally applied using PVD. A newly developed anodic vacuum-arc method ensures a substrate temperature below 50 Celsius.
