An electronic device has a camera assembly disposed in a housing of the electronic device that includes a light source assembly having a primary purpose for illuminating a subject during an imaging operation. The light source assembly includes a light source and a light window. A light block can be applied to lateral surfaces of the light window to prevent light passing through the light window from propagating along an outer surface of the housing, or other components of the electronic device. In some embodiments, the light block can include multiple layers having various reflective and absorptive characteristics.

The present inventions relate to the formation of a thin polymer film on a substrate. Apparatus is described for transforming a solid polymer resist into an aerosol of small particles, electrostatically charging and depositing the particles onto a substrate, and flowing the particles into a continuous layer. Apparatus is further described for transforming solid resist into an aerosol of small particles by heating the resist to form a low viscosity liquid such as is compatible with nebulization and applying the techniques of jet or impact nebulization and aerosol particle sizing to form the aerosol. A method is further described of using ionized gas to confer charge onto the aerosol particles and using a progression of charging devices establish an electric field directing the flow of charged particles to the substrate. The progression of charging devices and associated apparatus results in high collection efficiency for the aerosol particles.
