A surface (3) is given a coating (24) by moving it past a spray head (10) on a conveyor (2). The spray head nozzles (16), e.g. bubble jet, ink jet, piezo jet, and conveyor are under computer control through an interface. The material is pre-heated (21), e.g. up to 125 [deg]C, to achieve a suitable viscosity. Independent claims are also included for the corresponding plant and for surfaces coated by this method. A wide range of metallic and non-metallic material can be coated but specifically mentioned are optical components, especially waveguides, arrayed waveguide gratings and Mach-Zehnder interferometers. |
